And who is the ruler in 3250?
the texts suggest another wolf-ward-steiner-davion, though I suppose it could be a Kerenskywardsteinerdavion.
either way, it's pretty explicitly the Khan of the Wolves and I doubt they'd relinquish the Steiner-Davion heritage.
but beyond that, the mechanisms by which the system functions are explicitly Clan mechanisms making that the endstate dominant system with Wolf being the endstate dominant clan, and in control of the rest of the Inner Sphere, which puts them also under the Clan system, which pretty much defines how they got there. You used the HRE, but the HRE didn't even follow the FORMS of the Roman Empire beyond the name itself...which didn't last, becoming the Austro-Hungarian empire before balkanization.
To make it fit, your HRE in 1806 would need to cover everything the Roman Empire covered, including Britain, have a Senate, (albeit as a rubber stamp for the Emperor) the Emperor would have to rule with absolute power, and be selected in the same fashion, and everyone in Europe (and the near-east) would need to be using Latin as the language of business and government.
Oh, and it would have to be done within a single century, not over 1000 years.
What I'm telling you, is your equivalency isn't equivalent.
Part of the problem, is that the Clan system is one of those fictional constructs that can only exist in a universe founded on literary causality. Using real-life history doesn't work as a basis for comparison unless your fictional universe closely follows real-world cause and effect.
Battletech has giant walking robots, instantaneous FTL travel, and borrows a lot from 1980s anime for its physics, while heavily leaning on idealistic fantasy for its political structure.
The problem there, is that unlike in reality, in fiction, everything has to be internally consistent, and when you have exceptions to how reality works, you have to explain it explicitly in the story, as part of the story.
What was set up for ilClan laid out an internally consistent set of conditions-the outcome is, therefore, extremely predictable and doesn't leave much, if any room for surprises until after the 3250 report.
effectively, by bookending like that, it makes everything between 3150 and 3250 'filler'.
cheer up, I had the same issue with the Jihad once the improbability of the ROTS rolled out-they staged for a much nastier war than Catalyst was able to deliver, which was part of my decade or so 'finding something else to do'.
They had to fill that space, and so the war got a lot less brutal in order to give the impression it could go any way other than it did, and in order to leverage the results already seen in the clickky game's setting.
thus, the designated losers of the Jihad had to be very powerful-when not seen on stage.
In THIS case, it was set up for an easy walk BEFORE Hour of the Wolf, and there really aren't any factors that make it NOT an easy walk AFTER.
