Before anyone throws weight either way on whether a crossover would work, maybe we should see what Sonic's new book is going to be like? It would obviously be IDW's version of Sonic who would cross over with them so we don't know what it'll be like.
Honestly I still want TMNT to cross over with Godzilla if they're going to cross over with any other IDW book (that is, if they still have the license? I haven't seen a GZ book from them in a bit). Since Sophie's a kaiju fan (I know, more Gamera than anything else, but I don't know who has a Gamera comic license) she seems like the perfect fit for a book like that.
However I don't really care yet what they do with Sonic. They could cancel everything Sonic related except for the social media and Sonic Boom cartoon and be fine. They don't even need games.
