You should be able parallel two servos quite easily, and they really shouldn't have a problem sharing the load, but if you plan to convert the servos to continuous rotation, sometimes you can run into problems getting the motor to hold position at neutral stick. If you can get the potentiometer centered perfectly there will be no problems, but I do know that servos converted this way like to drift a little bit - correctable with a little radio trim adjustment. If you have two servos that are drifting opposite ways, they might be fighting each other at neutral, just a little. That's about the only concern I would have. It may not even be a big enough problem to worry about, but if there is a lot of drifting going on, both servos will fight one another and draw some current, possibly getting warm/hot. You'll have to play with a pair of servos and see what kind of results you get!
