I don't know if they'd let you do it, but feel free to ask on the Q&A.

I question the usefulness of locking the sticks together, though. If you tie them together so they are always in the same position, then it's no different than using a single axis. If you're trying to make sure both sticks move up and down together but move sideways independently, all you have to do is ignore one of the two Y axes in your code. What are you trying to accomplish by locking sticks together?
