The Mechs from the Unbound Adventure Book. While it was published under FASA, I don't know that it's considered any more canon than the events in Star Lord or Far Country.
The Japanese version of BattleTech. Kinda wish those were made into minis, and the fact that some were included in the Solaris 7 boxed set is a plus.
I admit that I like cross-overs, so the stuff from Nebula California is up my alley, too.
I liked the concept behind the TR: 1945, but I think the limitations of the system focus made for poor application to the tanks.
Now, if it comes to units from other franchises I'd like to see BattleTech stats for:
Kenner's Mega Force die-cast combat vehicle line. You've got standard vehicles from the 20th-21st century with some interesting sci-fi add-ons, like VToL Craft, and anti-aircraft tanks that can go vertical to get a higher clearance for its pom-pom guns. Then you've also got mobile structures, like the Scorpion attack tank with a unique looking hovercraft, the Brimstone ICBM launcher, and so on up to a giant mobile command center.
Heck, the
Thunderwolf is what I imagine a Planet Lifter to actually be.
I'd love to see the Infantry Walkers from Dirtside (VOTOMs in any other name). For that matter, Gears from Heavy Gear and/or the frames and ships from Jovian Chronicles would be neat.
Grav tanks and fighters from Centurion and Interceptor from the Renegade Legion universe.
There are many more - a lot of infantry suit looks that I prefer over what we get out of the source books, for example.
But I'll leave it at that for now.
