Here is an idea I came up with, it's not the best looking but it does the job. I had an old remote control sitting in the garage, so I took two of the buttons, grinded them down a bit, glued them to PSP buttons using JBWeld Epoxy. I then took two NDS buttons (this works with two PSP buttons that were left over as well), slightly drilled into the bottom, dropped some JBWeld epoxy into the hole, and then inserted tip of the tactile switch into the hole, let it dry.

This is the final result. Sadly I haven't been able to find buttons small enough for the XY.
