But, which epub devices would you be targetting? Sony PRS505 through to PRS650 family already have this feature in the PRSPlus custom software. PRST1 has it in Morkl's custom EbookReader app. All Kobos allow customised on-device font as a standard feature for main book text plus there's an option in the standard calibre Kobo driver which can be used to fine-tune 'special' fonts (e.g. smallcaps, dropcaps, monospace etc). Although I have to confess I'm not sure what Nooks can do with custom on-device fonts.
Modify Epub already has an option to Append extra CSS.
