I picked up a 55g from Petco last night and promptly took it home and drilled it for two 1.5" bulkheads. 2 x 1.5" is a little excessive for a 55 in my opinion but I already had the bulkheads for my 110g that sprang a leak before I could drilled it.
I then started messing with my 35g hex that will be replaced by the 55g. While messing with it I had issues with the DIY overflow pipe and got mad. So I lowered the water to about the half way mark, drilled the thing, put a bulkhead in and plumbed it to my sump then filled it back up. The only issue was the glass particles making the water a little hazy but my trusty huge DE filter cleared that up in less than 5 minutes.
I am not recommending drilling filled tanks and think it is a pretty stupid thing to do... but It worked for me.
