Shawn,
I have never met you so I have no idea what your personality is like. I would like to think that your post was sarcastic but I'll assume you are being serious.
In my opinion, I don't think glueing of any kind should take place. I'd much rather not be able to climb a new crappy V7 than be able to get on a classic re-built V4 with a glue on. But that's just me. I hope you will take advantage of this newly broken hold and treat this as a new problem to work on next season. Who knows, it might be totaly do-able at the same grade with just a bit different beta. I'm not familiar with the problem in particular, especially what it looked like before, but when I saw the first ascent of the 'new' problem it didn't look sick or anything. I know there had been some previous discusion this summer about Mega Man and the broken hold but I had not heard if anyone else had repeated the 'new' problem. I guess I was just wondering if anyone else had been on it to confirm a new grade.
This is a bad example because the Woodlot in Fredericton sucks but anywho. A couple of years ago I broke the key starting hold on Ogoshi V3. Everyone who came back to do the problem said it was way harder. But once I showed them some new beta instead of trying to climb the problem like in the past, they all agreed that it was about the same grade. I thought it was kinda fun and had a new problem to work on for a day.
Cheers!
p.s. Halifax bouldering rocks!
