Sounds interesting
Wilwood do an MC that bolts to the firewall, there's no way to get a booster on the firewall or in the engine bay and still have enough room for the engine and there's no room under the dash, however you can use a pair of remote boosters and fit them in the boot

Brakes would definitely need an upgrade, I have a pair of rebuilt gt struts that have large vented rotors and 4 piston calipers

The little borg warner diff will have a hard time dealing with anything that resembles torque
And are.you sure it has a collapsible column ?
