47cm Parabox Skeleton Hybrid with AP Soft Skin Parts

I’m wondering if it’s possible to use a parabox 47cm and hybrid with soft skin AP parts (chest, lower torso, and thighs…. maybe arms too) would this be reasonably do-able? I know AP are on the 48cm skeleton, so I assume I might run into some issues with the legs? 
Are there any other differences in the skeleton that would make this not work? 
 

I appreciate any advice!!

I've never owned this body, but generally speaking, the Parabox bodies use the same skeleton. The torso (so anything above the hips) should be identical. The snag is in the legs. Each body's leg "bone" is factory trimmed to fit the outer shell. There's some leeway, but I'd rather have it be too long than too short.

There's a possibility that the leg "bone" will be too short, but even in that worst case scenario, you'd just have to buy the leg skeleton part and re-trim it yourself. It may be possible to pull the "bone" pieces out of the sockets a bit and make up the difference.

Personally, given that you sound like you're replacing every outer shell part except the shins, I'd just start with an Obitsu 48 instead.
