tamer I'm assuming that you are refering to this:
and while I've also commented on the similarities between the two the size variation is huge between the concept art and any version of the hiss tank. Although, the height of my latest kit bash comes closer to the concept art, there are alot of things that stand them apart... I just don't think the vehicle I created would fit into that concept's role...
When I think of star wars I don't picture treaded vehicles, to be honest I think the only wheeled, or treaded vehicles in the entire saga (at least the only ones that come to mind) are the jawa sandcrawlers and then the turbo tank. everything else is either walkers or repulsorlift driven.
To be quite honest I'm starting to wane away from star wars customs. The newest lines of figures are great, but they truly pale in comparison with the POC wave of gi-joes.... Thus, I've gotten into a joe mindset of collecting and customizing more lately than the star wars end of it.
anyways. I guess the hiss tank could be a crossover vehicle. There's no reason it wouldn't fit right into the star wars universe. It's futuristic enough I think it'd work well.
