Looks like an interesting conversion, but I'm wondering at the point of it though... ;-)
The Fujimi chassis is not really that detailed, and is only a curbside itself, so you might end up with some suspension details that the Fisher kit didn't give you? It will be difficult to cut open the resin body to display any internal detail, although if you do manage to lift the engine lid, I believe there is an HRM resin engine you could use with the Fujimi chassis, but you'd be looking at a LOT of scratchbuilding in the engine room...
When I built my Fujimi 917, I found the front suspension needed to be lowered about 1-2 mm to get a good stance. Looks from your pics that the same might apply here.
Good luck; I'll be interested to see what you make of it,
