Porsche brakes on 1303

[Tim]

I plan to have following Porsche brakes upgrade for my 1303 which already has the 944 suspension conversion.

front:
911(83-89) discs on early 944N/A hubs and spindles
Boxster front calipers with custom made adaptors

rear:
944 alu arms with '86 hubs
993 discs
964 C2 two pot calipers

Questions:
1) The 911 disc is 282 x 24mm. Would the Boxster caliper be workable as it is supposed to work with the larger Boxster front disc 298 x 24?
2) Does anyone try similar setup as the rear I proposed? I just conceived the idea based on the measurements info of the parts which I found from various sources.
