Hm, interesting question/thought. I almost wonder if he wouldn't have been और swayed towards Gryffindor, simply because at a young age people tend to be और influenced द्वारा their own gender. So with a male friend already there it might have held a greater appeal. Not to mention if guy Lilly makes फ्रेंड्स in Gryffindor then there's the added appeal of a peer group he could join. Of course it could have gone completely the other way and driven him further into the Death Eaters.
