I am surprised by the values you assign to Aanca / Gryphon. They seem too low. I measured only on 8x8, and IIRC on the Kaufman scale (minor = 3.25, Q = 9.50) the values I got were Aanca=7.8 and Gryphon=8.3. And as these are sliding pieces, they should benefit just as much from larger boards as Rook and Bishop. An Aanca covers more squares than two Bishops (positioned left and right of it) would, so I would expect its value to be at least double that of the Bishop. It is also not color bound.
Because of the up-shifted starting position the board of tehse Grand-Chess-like games is effectively 10x8, and wide boards benefit diagonal movers more than orthogoal movers. (This because the chance that both their forward moves hit the enemy increases.) I would not be extremely surprised as an Aanca on a cylinder board would be worth more than a Gryphon.
