Here are a couple more at different stages of installation.
Thinking about the hybrid idea for an MG F, you could use the entire rear motor and differential from an Outlander Phev. One of the reasons I didn't use the differential was that in the Outlander the motor hangs rearward of the differential, so in the MG I would have had to install in backwards.
If you were to put this in the front subframe then the weight would be towards the middle of the car rather than hanging off the end. Assuming there is space for it. Space would still be a bit issue in order to fit in batteries and the inverter. Another alternative could be a tesla small drive, those have the inverters built in which saves some space. Would just need to find space for batteries then.
