The control scheme is not at all likely to be changed, and options for it are very unlikely to be added.
A way around this is to add the game to Steam, open Controller Configuration, change your left joystick input type to Directional Pad, assign the 4 d-pad buttons to the 4 directions, change your right joystick input type to Directional Pad, and assign Left Trigger to left and Right Trigger to right, leaving up and down blank.
