No, 'cause it's already GOT an aluminium engine - well, mostly. The oil pan's magnesium alloy (even lighter), other parts are carbon fiber - and it's 1000 cc.

The battery pack isn't all that heavy, maybe 50-60 lbs for the pack, maybe another 40 for the power converter electronics. The electric motor replaces the flywheel of a normal engine, so not much weight added there. There just isn't a whole lot of room to take weight off the frame & powertrain. About all I can think of is a radical body redesign, much lower & a bit narrower, like for instance the old Lotus Europa...
