Considering purchasing a GL2 for two camera shoots with our XL2 at weddings. Do they match well in editing?

I think you can match them resonably, but if I'm not mistaken, someone already asked such a thing, do a search maybe.
It's not a very hard problem, if you don't film in 16/9 on the XL2, and don't use 24P on the XL2.
(30P could mix well with Frame Mode on the GL2).

If you white balance them both manually, it shouldn't be a very big problem.

I did a little search for you, try these:

Good luck.
