LOL Mario - that's the spirit - don't let this lick you - its worth it to get it all going!
I'd suggest a simple experiment to see whether a cut down adaptor will work - take out your 1.25 or 2" adaptor to leave just the focuser, attach the MPCC to your DSLR T-Ring, point the scope at an object at least 500m away (or a star at night) and see if you can reach DSLR prime focus with the MPCC right up against the inside of the focuser adaptor (with focuser right in) - you'll be looking through the camera viewfinder to judge this of course.
For me, infinity focus is about 8mm back from the max "in point". As long as you have at least 5mm or so then you can get it to work by cutting down the 2" adaptor - mine is now 22mm high - I could dig out the name of the place that did it if you want. Just be aware you end up with a decent amount of your focuser tube down in the lightpath, but I haven't seemed to suffer too much because of that.
Brendan's mod is intruiging, but I'm surprised there was that much metal to take out. Theoretically it should be the best fix as you can use other 2" accessories and eyepieces optimally. I'd suggest a private message to Super Bbrendan (Bmitchell82) - he is often on the lookout for jobs to perform like this at reasonable prices. You'd have to post to WA, but he was very prompt machining up an adaptor for my finderscope/guidescope.
