Be Incantatrix. That'll free up your normal feats for Font of Inspiration, as Incantatrix pretty much gets all the metamagic you could ever need - they get like 4 bonus Metamagic feats. Also, use your Wizard slots to cover the rest of your needs; 1st and 5th can be martial feats (through Martial Wizard) or metamagic or item creation - although Spontaneous Divination over 5th would be really sweet - so use those slots to get your Wizard feats while Factotum goes Fontsane. You'll really want to eventually have 4-5 Fonts, so you'll want Wizard-levels to pretty much provide their own feats (a great reason to play Incantatrix).
