that is pretty friken sweet, though I personally would prefer an uparmoured AT-TE (so it looks almost like a kitbash of an AT-SE with an AT-TE configuration), I would love to see a dedicated repulsor tank vehicle though (no infantry carrying capacity), maybe with Treads or wheels as an auxiliary drive system.
maybe something in the 5 meters long area, like a modern MBT or such, for Urban warfare, something I could see rolling down the streets of Cardassia prime or Qonos
maybe shoehorn that AT-AT gun on it, love the sponsons and Warhammer 40k like configuration with Imperial technology though.
be fun to have something similar to an AT-SE but with Turbolasers on "arms" like a Warhound Titan XD
Star Wars Titans, be like corvettes on legs XD
wonder how much power they would have by comparison, I mean on the one hand they are allot smaller, but on the other they don't have to worry about Hyperdrives and huge ion engines,
maybe have weak repulsors to reduce the weight and improve their speed and agility.
