Haha, definitely possible, there should be enough space to fit a TRS or XLR plug - unfortunately, I don't have the tools necessary to make the holes. Ideally you'd need someone with a drill press and the proper sized metal drill bits as the aluminum front panel is pretty thick. Beyond that, when attaching the internal cables, you're going to want to make sure it's well shielded running back to where the speaker taps connect because the power transformer is near the front. As for the resistor setup, I can't say what would be optimal so you will have to do further research here, but you will likely want wirewound resistors in an 8-10 ohm parallel (positive to negative wire for each channel) with a high power rating and then a resistor in series with each positive channel. I imagine it would be similar to the HE-Adapter http://head-direct.com/Products/?act=detail&id=104 except each channel would run thorough a switch where you can select to bypass the resistors for the output to the front panel connector, and a second set of switches further down to select use of front panel or back panel output. Trust me, I had thought all about it when I had my Mini-X, but never went through with trying any modifications. For those brave Mini-X users out there I say go for it, you could start a revolution!
Sorry for the crude MS Paint drawing, but I think something like this would be optimal:
Just remembered that the ground is shared, so the negative channels would technically meet at the same point on the amp source, just not sure where exactly. It could be traced from the speaker tap connections though. If anyone else has any more insight on this, please share your ideas!
