Yes I think is possible, but the motors are not that powerfull (only 3.6 kg-cm torque), so start out by making a small version first.
For instance I used these motors from Pololu: Pololu - 30:1 Metal Gearmotor 37Dx52L mm 12V with 64 CPR Encoder (No End Cap) which has a torque of 8 kg-cm.
Also I think it is weird, that the peak current is not listed on the website or in the pdf (http://www.robotshop.com/world/PDF/rbsol03_manual.pdf), but if think the motor controller will be okay - if it get's very how, then add a heatsink.
