Bulgaria isn't an option here (not contiguous, never tried to claim it), but Italy is, since they tried to colonize Southwestern Asia Minor in OTL.
İzmir is a bit difficult to judge because the city itself was probably plurality-Greek during WW1, but this was an extremely recent development (the 1880s Ottoman census shows a Turkish plurality) and the overall sancak was majority-Turkish. Overall I think it's better off in Turkish hands since a hostile countryside would be terrible for İzmir's economy, but it's a messy situation all around and the OTL expulsion of the Christian majority there was a definite tragedy.
But in terms of the vilayets in question in 1914, İstanbul vilayet was majority Turkish, Edirne vilayet was majority Turkish, Aydin vilayet was majority Turkish.Either way, it's not remotely fair that Turkey got all of the disputed territories (Eastern Thrace, Ionia, Constantinople) after WWI, and Greece got none of them.

Smyrna could be propped up with imports from mainland Greece.
