I would think its possible to build a good fork from the pair but nut 100%. the SP is a pain on the road as the high first gear is like pulling off in second, its great for the track as it pulls all the other gears closer together.
The SP cdi's are super rare so the best thing to do is split the engine and sell me the gearbox.

I will check the number on the one i have but it is easy to tell as the SP cdi has one 12 pin connector not the smaller two of the non.

Theres a CDI on ebay, from wemoto. I think there trying to get rid of it because its up for £120.

I believe my road bike has an sp bottom end (can get over 60 in first), but it has no other sp bits.
