For two identically geared engines, ignoring mechanical losses, you simply sum the two torque curves to get your overall torque curve.

For differently geared engines you need to calculate the rpm's across the range of rear wheel rpm's and sum the torque at those rpms for each engine. The problem you have is that the higher the revs, the bigger the difference in rpm's for each engine meaning there will only be one point throughout the range where you have "matched" the curve of the engines. You also have the situation where one engine hits peak rpm before the other.

There may be situations where it is of benefit, but I can only see it working at very small gear ratio differences.
