15/47 on 12 cells with the xl1600 will put you at around 29mph. The 1/8" shaft and 5mm pinions is a snafu, though! I have 1/8" bore mod1 pinions, but they won't hold up to the hardened spur gear. I may have found a source for the hardened mod1 gears, but I need to do some research tomorrow to see if I can get them in with a 3.17mm bore (1/8"). If you go with the 15/47 gearing and a parallel set-up as you had mentioned, I would go with the 8L motor.
