Just saw this and it makes you wonder if they could do it to an XK. Looking at the cars they converted it seems like it may be doable. Take a look here. https://www.gatedsix.com/forsale

 

Supra with a $6000 'deposit'.
Anyone can do anything to anything if they have enough money.
I'd not pay an additional $20k or whatever to have a worse vehicle.
Similar to 'Rat Rods' where people make, uh, 'cars' out of parts, but end up spending quite of bit for a worse-than-before trash pit, and they do this On Purpose.

 

For that much $ I would do an AWD conversion instead =)
