I wouldn't personally be modest as to suggest the panthercraft as a potential candidate for turboing.
we have a set of panthercraft hulls at the club and it you press your hand against them amidships you can actually push the sides in at least an inch if you try hard enough. I have heard reliable accounts describing how the hulls would actually visibly 'ripple' when beating towards the top mark. I'm not sure they had any significant bulkheads of any kind! but the reg white platforms are a different story. there were combinations of foam sandwich / nomex sandwich and skinny beam / fat beams. obviously the thicker beams are preferable, and our local fleet has about 6 boats that have been converted to the SPi rig successfully. the Reg White hull shape seems to be quite compatible with the new rig. to know if you have the big beams they look almost like a W shape on the top side. in any case good luck with your project, since I've entered T's I've met some of the best people and sailing the boat is just one of the things you should do if you're into sailing.
