Glass Platter for Rega RP1

Does anyone know if there is a Glass Platter for a Rega RP1?

I see that ND has one for the P3 and P5 but would it be compatible with the RP1? - http://www.needledoctor.com/Rega-Glass-Platter-for-P3-and-P5?sc=7&category=23669

I know many people have upgraded their P1 Platters and I would think that you could do the same to an RP1, but I can see how not very many people would upgrade to this bc it would make more sense to just buy and RP3.
