some of the old willys gassers that had alot of engine set back i have seen them mount the throttle pedal on the trans tunnel and the clutch in the foot box and a hand brake!! in some extreme cases anyway. but from alot of pics ia have seen the throttle pedal up on the tunnel was somewhat popular with either a hand brake or two small brake and clutch pedals. depending on if this will be an auto or stick. but thats for an all out racecar. what are you trying to turn this car into?
