It is possible but there is a crap ton of work that has to be put into it. Electrical and mechanical. Relocation of the brake master/booster assembly is tricky. There is a rod attached to the pedal that transfers the mechanical energy from the pedal through the booster to the master cylinder. You would have to find a way to move it while retailing the mechanism itself. And you don't want to move the pedal. On top of that there are few places in the engine bay that have enough space for the booster.
