So we ended up doing is making our own Gaussian function to adjust the y speed based upon the angle of the x and y vectors from the joysticks. The major downside is that we won't be able to go diagonally at "full speed," but as you said, this may be something we'll just have to accept.
We should be able to actually test this approach on tomorrow and I'll try to update this post with the result.
