I found the nerve to do it. Actually it was a piece of cake!
So much that I now call myself stupid for not having done it before.
It worked a treat, and the finished work looks MUCH better than the photo samples I saw on the net, and now I can mount ALL my lenses on the 5D!!! 
yippie-ya-yey!

Yes!!
It's very easy. If one like me (totally helpless with hand works) could do it, everybody can.

I didn't have the time to make a photo reportage. But it's really simple.
You need:
- some fine sandpaper
- some plastic sheet, best if thick (that used for storing food in freezers was good for me)
- a little masking tape
- scissors
- an air blower
So you cut a square sheet of plastic approx. 8-10 cm the side, fold it half and on the bent side, make a cut with scissors, long about half the width of the mirror. So when you unfold the plastic sheet, you end up with a cut slit in the centre, long like the width of mirror.
Take the 5D, manually raise mirror and insert the plastic sheet through the cut slit. Pull down the plastic sheet, so that the mirror surfaces enough to leave room for the masking tape.
Now, you cut two small pieces of masking tape, same lenght as mirror width. You take one and apply it part over the upper side of mirror, part over the plastic sheet. Do the same thing, with the lower part of mirror. Now the plastic sheet is secured around the mirror, and no space is left. The plastic sheet surrounds the mirror more or less like when you see surgery in movies, you have that sheet with a cut that leaves open the part where surgeon operates, now we have the same, a plastic sheet that covers everything except the top part of mirror, which we will operate. The plastic sheet makes a little concave around the mirror, due to the camera hole, this will collect the debris.
Now cut a piece of sanding paper, fold it until it's small enough and comfortable to hold, and begin to sandpaper the top of the mirror. This means both the actual mirror, and the plastic housing. If you use a fine sandpaper, which is recommended, you will obtain a very good looking result. You need some patience, no hurry, because you don't have to force too much on the mirror, else you may damage it. Go on sandpapering and every once in a while, rotate camera so you don't always sandpaper in the same direction. When some debris accumulate on the plastic sheet, blow it away with the pump.
Proceed like this, until you have erased about 1mm. You keep close to you, one lens that you know does not clear mirror. So when you think you are ready to make a try, blow away debris carefully, remove the plastic sheet and mount the lens. Should the mirror not clear yet, it means you need to work more, so cut another square piece of plastic sheet, and repeat the procedure above described.
When you test and finally you have positive result, you are over. Just make sure to always pump away debris during the work, and when you have finished, raise the mirror again with your finger and pump well inside the camera - the sensor whould not appear, it should be covered by camera curtain. Blow much around all spaces inside the camera hole, just for safety.
Voil? now enjoy Helios-44, or MIR-1V, or Hollywood Distagon, all focused to infinity on your 5D

Orio, you're the man!
Even if you say that it was easy, I think it was very brave.
Congratulations to your successful surgery!

I decided to do it my way. I was adviced to use rotary stone and file, but I didn't like the aesthetical result of the file work I could see on a web page. So I decided to go with a fine sandpaper and I am glad I did, the work looks much more professional this way, the little mirror scales that you see have gone away on the edge, are really very small, because here you are looking at a big enlargement compared to real life size.
In real life size and normal light, you almost don't notice the job.

Congrats, Orio.
You must have felt a big relief after finishing the job safely. 
I wish I had a 5D to shave its mirror (but I don't think I'd dare)

Thanks.
Not really, no relief. I was very determined and very sure about how to do it. I had no doubt it would turn out ok.
