From the description (both here and of the Sliding General), shouldn't it be a three‐path lame dabbabah?
Well, the description was KtfsF, so I assumed a W as second step was out.
Another enhancement I had considered was to just add the Wazir move to the existing Griffon pattern.
That was the first thing that came to my mind as well, but I was afraid this would make it too strong. IIRC the value for the Griffon I measured was 8.2, and 4 extra moves easily up the value by 2 Pawns, even for a Rook. Just bending a trajectory in another shape is more like adding extra squares at the end of the trajectory: all the normal Griffon move now become more easily blocked. This should partly compensate the effect.
