If your case is a bit bigger and also a bit thicker, no, not that hard really.
However, I used a small case, positioned the joystick out too much, and made the case as "slim" as could manage, so made life difficult for myself.
I would take a commission or two, however would only make one on if it was worth my while, as it would take a long time to make and deviate my enjoyment from different projects. I have made the guides comprehensive, enough for someone to make their own portable if they wish to do so. In saying that I may make a system or two and offer it to the highest bidder from those that have expressed interest, at some point.
You say you've looked on the PDF files, good, have a look on the video logs, they are easier to follow.
