Help needed: An "Old One" melded to a Summoner

[Coltaine]

I need help implimenting an ingame concept. In my current campaign, long ago, a cadre of mages summoned Old Ones into themselves, melding the two together in an attempt to gain power (due to "benovolent" reasons; i need to impliment this in game. Any ideas?

First thing that comes to mind is the Synthesist Summoner archetype in UM.
