I've submitted a ZRF for Mike's Camel Chess--a variant with the enhanced
Diagonal Bypasser and more limited Tower of Hanoi as defined in my
previous comments. It seems to be considerably more playable, but
preserves the essential flavor of Lùotuoqí.
The biggest difference between Lùotuoqí and FIDE Chess (IMO) is not the
Tower, the Bypasser, or the Cube but the Eaglet promotion rule--promotion
is possible early and will normally occur on the player's own side of the
board.
