I've done it in thirds once, it was a LITTLE easier but it certainly wasn't "easy", at least it wasn't for me. I've seen pics of members posting their quilting done on their home sewing machine and they're beautiful, but I can barely do a generic meandering. Maybe I should stick to just making tops. LOL
I didn't have any problems matching the sections of the batting together though, so give it a try if you can. If I can do it, I'm sure that you'll be able to.
