Pacquiao vs Margarito w/ loaded gloves?

Hey guys, Me and my friends were talking about this, thought i'd get some input. We all know Margarito will get hit a lot and will easily lose via points and Pac's legendary stamina should enable this to happen. However if he is able to walk through Pac's punches like he did to Cotto, land his own bombs for 12 rounds, and keep Pacquiao moving BACKWARDS (unlike his recent bouts) it could be a long night with a brutal TKO ending in his favor. Obviously this scenario is now impossible, but if Margarito's hands (which somehow went unnoticed for 40 some fights) weren't discovered, we would've seen this fight already and could have a massive impact on our fight scene now. Thoughts?
