Ideas are plentiful. But a system where different legs of a move each have separately indicated atoms fits more with the proposed Betza 2.0 extension than with the XBetza extension that is described here. (And which only mentions the start atom, and describes the remaining legs of the move through modifiers.)
What you propose is not precise enough to be flexible; it doesn't describe which directions of the Rook move can follow the Ferz. E.g. what if you want to have a piece that should only bend in one direction (a chiral half-Gryphon)? And what if the second leg is not a Rook but a Nightrider? The angle(s) you can bend by must be explicitly specified, and just using symbols like < and > doesn't give enough possibilities.
