If you do something like this you need to decide on
1. Cost
2. Weight
3. Combined HP
I would guess for weight a 1.9tdi, a 1.2TDI or any of the antique non-turbo VW motors would be fine, even an Olds 6 banger (inline or V) 4.3ltr diesel would be fine and reliable (5.7s were not). The Isuzu diesel found in Chevettes is also an excellent choice for pure economy. If weight is critical a forklift or industrial diesel may be on order.
If weight is less of an issue the 6.2 or a 6.5 modded for fuel economy might work or the Cummins 4bt if weight and price are not an issue.
But if you use any of the above you will need
1. A HD FWD setup like found on the 350v8 front wheel drive vehicles.
2. A direct drive RWD EV setup.
During drags you will have to tie your throttle for the diesel with the EV and use both to take off. (4wd) You will need switches to kill the diesel or the EV portions and add a sensor to your brakes for regen.
You can have a generator on your motor but understand that it will likely kill your FE and not be efficient, better to have a completely separate EV side on a separate drivetrain that you can control regardless of the diesels activity. (think of MIMA that can run when the motor is EOC)
Good Luck
