Help with Drilling Acrylic Sump

[wetcoast]

Wondering if someone with a bit of experience would be willing to lend me a hand.

I have a sump with a 1.5" outlet installed that is going into a Reeflo Snapper. The intake of the snapper is 2" and I am trying to curb the obscene amount of noise this pump is emitting compared to my dart. My question is, how easy would it be to drill expand this hole to support a 2" Bulkhead? And does anyone have any experience with this?
