You do realize making a circular and hexagonal hole is not 'a ton of work', right?
You are forgetting everything down the line that needs to happen... Changing the model that much will probably require new UVs, then there is everything involved with the conversion process and getting it into the game.
But if it's really not 'a ton of work'... why don't you do it?
No, I'm pretty sure the UVs would be mostly preserved save for the hole and area around the hole, unless it's an import/export issue.
Anyway, I'll gladly do it as soon as my main comp is fixed. I've not got anything other than sketchup on here.
On the off chance that I get max to run, it will likely lag so bad that doing anything will be pointless.
