In the set up I proposed the ICE and electric drives would be independent from each other linked only by the ground. You can find a similar setup in theory although swapped electric powering the single rear wheel in the XR3 hybrid plans. Things always have a way of seeming difficult and expensive until you decide to find a way to make it otherwise!
In order to make it worth while the car has to be light 1,200lbs or less and aerodynamic in fact extremely aerodynamic like a cd of 1.4 or better. This allows a 2 cylinder or 1 cylinder diesel with a 10kw continuous -20kw peak electric motor to be used with only a 2 kwh battery pack! This gives you a descent battery only range in excess of 20 miles or better depending on how you drive. If you are like me and drive like a G-PA you could probably get about 30 miles EV only! The VW XL1 I think has around a 4kwh pack and gets about a 40 mile range but its cd is higher and weight is also higher than what I propose.

50 lbs of battery for moving around 1200 lbs of vehicle seems very few.
There is a VE 4 wheeler currently sold by Renault under the name Twizy.
Its top speed is a little above 50 mph, range is in the 50 miles ball park weight is 900 lbs or so.
It is not really aerodynamic but it is not of primary importance where it is supposed to ride.
I bet it has much more than 50 lbs of battery !
I also bet you can have more range than the 50ish if you ride it adequately.
