@Lady Lascivious, be Greece's patron? :P
So historically, Greece was usually under the patronage of three powers in Europe:
- The Francophile faction, which was usually aligned in the more conservative powers of Hellenic government and favored a more gradual shift of the country into modernity after Ottoman rule.
- The Liberals and Irredentists, who found themselves being found under the influence of the British.
- The reactionaries and Orthodoxists, who liked the strong power of Russia's status and mutual orthodox heritage to, again leverage power against the Ottomans (I think you're noticing a pattern here)
OTL the conservative factions in Greek politics would largely end up winning internally, but Greece herself was by in large under the whims of a British establishment - who in turn would end up being pro-Hellenic more often than not, due to the interests of the expanding Greek state likewise also serving as a natural check to both Russian and Ottoman interests in the Balkans. In that vein, your best bets for any fruitful alliance here would most definitely be Britain, who was very interested in a Hellenic state who could fulfill that role.
