Integration of Inventory/File(JSON?)/Economy APIs with FSMM

I would like to request a plugin that uses SpongeForge’s Inventory and File(JSON?) api’s to integrate Fex’s Small Money Mod with SpongeForge’s Economy api.
File(JSON?) api is needed to integrate FSMM’s banking feature as FSMM uses a config file (JSON?) to store bank balance.
The banking feature also support’s multiple/different banks and virtual accounts.
So ofcourse implement FSMM virtual bank accounts for virtual economy balances used by other plugins such as Nations.
