The idea behind 'bi' is that the piece jumps to the 2nd square before sliding. I still like 'ski' for describing such pieces because it's more general. You could describe the Tiger Chess astrologer as a ski-osprey, for example.
For represeting these pieces, I've been thinking of something like this gryphon.
The central X could be replaced with a small dabbabah/alfil/knight/whatever to indicate the first stage of the move, while the rooks or bishops in the corners show the second stage. That might not work so well for the ski-queen though.
