No idea about 3-way. I'd guess LA+3 (not LA 4, because the overlapping should get significant), but by the time you're gestalting 3-way, I think things start getting homogeneous... as in, all the characters are basically the same. Everyone will have at least a d10 HD, everyone will have all good saves, everyone will have full BAB, everyone will be a spellcaster, etc. Doesn't sound interesting to me.
Note that PrCs can only be used as ONE portion of a gestalt, and the rest must be base classes. Racial HD takes up all parts of the gestalt (due to the augment clause).
