Don’t think so, beyond the fact that making frames isn’t trivial and modders just haven’t gotten to all of them yet.
Only wondering because they got Frames Like Caliban, Atlas, Zheng and Emperor attempted, granted those are still in the 1.0 versions. I'll download them and see what the fuss is on those. Kolbold seems oddly missing, though I want to attribute that to the fact that seems kind of outa scope from what the base graphics can easily be repurposed todo. thought I'd ask.
