Looking at this again, there is canon support for it, though. Arguments could be made about how the text is presented in the Horse and Mandrill sections, but the trial as described in FM:WC's Coyote entry states that the Smythe-Jewel commander "rearranged his force composition and deliberately led his opponent to believe she was going up against a much smaller force.
There's a definite lack of wiggle room there. I have to be careful reading these texts as a Mandrill fanboy as opposed to a neutral observer. It's too tempting to jump on the opportunities offered by the more ambiguous statements. That said, I'll try to offer up a few inconsistencies that should (personal preference*) have encouraged a more subtle approach for Smythe-Jewel's bidding.
One (admittedly thin) thread I'm clinging to is a small passage from the Lancelot C entry in TRO: Golden Century. Emphasis mine.
"...when it won possession of OmniMech technology from Clan Coyote. Then-Star Captain William Smythe used a pair of
Lancelot Cs alongside light 'Mechs to give his striker Stars more
size and firepower than the Coyotes expected."
"...
These tactics and inherent advantages led to a Mandrill victory, but
the devious bidding employed by Smythe would eventually lead to his Kindraa's demise and..."
We could read "size" as either tonnage, or number of 'Mechs. I don't think there is a strong implication towards either, but I would have read this intuitively as the force composition of striker Stars shifting away from light 'Mechs and instead replacing two of the five with unexpected heavy 'Mechs. As opposed to simply increasing the number of 'Mechs to 7.
This is the type of force composition monkeying that I want to believe was being performed.
I include the second quote more for semantics than content. Given "
these tactics and inherent advantages" (advantage was described as weight and range) would suggest that it is the tactics described in the entry that led to victory, and "
the devious bidding" also suggests that the deviousness the text is referring to is the same described above. To be fair, the exclusion of "the" would suggest otherwise, so I'm hinging more than maybe I should on that single word, but along with the rest of the entry ...I want to believe!
It's not a huge stretch to believe that these individuals (or their second-generation protégés), having lived through or directly heard about the formation of their Clans and the resultant massive societal and military changes, could have been more flexible in their implementation of Kerensky's tenets.
Then, if we consider the way the author presented the Smythe-Jewel warrior's response to Smythe's surprise reorganization we get the impression that this instance was the
first time they had encountered this sort of behaviour. Jewel is shocked, and considers the reasons for why Smythe had "risked so much with his batchall", which again would suggest this is the first time the warrior had been made aware of this behaviour. It all comes down to producing this impression that the warriors present for the Trial are
surprised by how far Smythe stoops, which - if this trick had been pulled in a similar manner with the Coyotes before - should not have have been particularly shocking.
Amirault I could understand being unaware of Smythe's tricks, after all the Coyotes had been "notably silent" about the business and it had been
18 years (6, my timeline was waaay off) since William Smythe's victory of Coyote - which would have provided more than enough time for most of the stories/outrage over the OmniMech Trial to fade away. But, the warriors of Smythe-Jewel at the least should (opinion*) have had some inkling of what had happened previously, and recognised the ruse from their last (incredibly important) victory.
But all this odd behaviour might just be a symptom of the strange lack of information regarding the Smythe-Jewel vs Coyote OmniMech trials in the story. Given how important winning OmniMechs should have been - with the failure of the other Kindraa, how it massively altered the Mandrill/Spirit relationship, and the stated similarities between the Horse and Coyote Trials - I feel like its absence was a deliberate choice by the author (easier for continuity later?), and could be the reason why the insane extent of the deception reads as fresh to the Smythe-Jewel warriors. To be fair, the outrage of Jewel and the other warriors would have been reasonable the author had chosen to give us a peek at the OmniMech Trials, but they may have built up a bit of a continuity pickle for whoever writes the Coyote encounter.
And of course, all this assumes that "smaller" in the Coyote section of FM:WC isn't referencing the number of 'Mechs. Which, right from the get-go requires a more...creative interpretation than any of the arguments I'd presented.
