Something like the now discontinued Fender Acoustasonic might work well for you - it's a lightweight hollowed out Telecaster shape that uses a piezo pickup.
You'll need an amp, too, with this guitar. An acoustic amp like a Fishman Loudbox mini would probably work well here.
Of course if you REALLY need a guitar with a tiny lower bout, check out the Steinberger, which has taken small body electric guitar design to the nth degree.
