Great, now I've trapped my goose. :P

Yes, I did mean dragon horse, not dragon king. I'll play around with the RC/SC idea and maybe some other combinations. Would it be a bad idea to also get rid of a jumping piece and add another general or two (maybe a stone general/iron general)? Or that piece could replace the gold cannon and lance instead, replacing medium strength pieces with weak pieces instead of getting rid of them altogether. That might be a bad idea, but then there would be more generals defending the king, like other shogi variants have it. I haven't given the idea a whole lot of thought, so it might not be very good, but I'm just brainstorming...
