Reducing to 8 ranks would increase piece density still further, of course, from 24% to 30%. However, I'm not sure that piece density is the problem that it might look when half the non-Pawns are both short-range and bound to a quarter of the board. Even given how much stronger Carpenters are than Knights it's not really FIDE-and-a-half army - although if I do an 8-rank version I might remove Carpenters from that.
Knavish Shatranj sounds an interesting idea. I may add further analysis here of the relation between Knave and Debtor bindings.
