You are on the right track. With completely stalled motors, the electrical model collapses to a pair of resistors in parallel. As Russ said, dynamics make the model harder. However, I don't think it is nearly as hard as he makes it out to be.
Tomorrow I'll try to put forth a better response, but here is the quick and dirty:
Assume your transmission perfectly lock-steps each motor with each other, so their speed is identical (or is at least a constant multiple). You can now sweep voltage and speed to get current and torque.
