That would be a lot of work, more than altering the driveshaft. It would also put the engine back from the radiator and possibly pay havoc with the power steering and ac hoses.

I think not recommended.

A good thought though.

(The handling of a stock 123 240 is very balanced to begin with too, IMHO)
