Yeppers...it's only a hole to get a piece of pipe thru that will be
covered up anyway. No sense in making a monumental effort here; spend
the time and effort where it'll make a noticeable (and useful) difference.

how about cutting a @ 2 1/2 inch in a piece of 2x4 and
screwing that over the center of the 2 inch hole, and using
the 2 1/2 inch hole as a guide..

This is the standard way of enlarging a hole. I use scrap 3/4"
plywood as it's less likely to create problems of depth, you can use
the ubiquitous 1 1/4" drywall screws to attach it, and the plywood
won't split with repeated use.
