Good idea on using LEGO's to make seats. I knew that I saw someone post the modern Thundertank before but I couldn't remember where I saw it.
I think I'm going to be on the look out for this to go with Mum-ra's forces.
For those that may not have the funds to shell out for the Thundertank on AFX, Target has the modern Thundertank on clearance right now. I found mine for $14, but YMMV. I think it will suffice as part of my MM Thundercats display.

Long time lurker, but I figured this is worth a post.
I found him at the Disney Store in Orland Park, IL. They didn't have the other set out, but I wasn't passing on this.
