599 steering column extension

Hi,

I have a 599 GTB and can never quite get comfortable, whatever it is with my body proportion I can never get the feet, hands, bum and head placement just right.
If I have my hands just right for the steering wheel my feet are too close to the pedals or I have to have the seat back very straight.

I've looked into extending the steering column but been told by a couple different people it's not possible. I guess it would also affect the gear shift paddle / steering wheel spacing as the well as there not being enough length in the loom?

Is it possible to move the pedal box?

Thanks for the suggestions and experience
