I imagine it would work fine. Recently, I was working on a plan to mod AndyMark 2-speeds to add FP w/ AM planetary, in addition to the 2 CIMS; when I "ran the numbers" (ie used JVN's old calculator to model the combiner), the load was perfectly acceptable. My gearing plan slightly different (faster low gear, slower high), but the predicted FP current draw to slip the wheels was 13 amps in low gear and 32 in high. I wouldn't want to get into an extended pushing match in high, but the motor should last fine if you try to only push in low.
