I'd like them as household troops for a 40K Rogue Trader if they were a bit cheaper. They somehow have the Rogue Trader future-yet-retro-swashbuckler look to my eyes.
Mixture-of-epochs looks to me like they could be shoehorned into anywhere from Lacepunk to 40K, given a fair amount of player tolerance. Not entirely my cuppa, but I could give some explanation, IF they fell into my lap, painted, for next-to-nothing.
Oh, wait, that's old Star Wars/Mage Knight/et all. figs...
