Share some good photos of your existing bike and 26er wheelset and we might be able to tell you if you can fit those wheels into the frame or what changes might be required to put them in the frame. If you can get those wheels into the frame the bike will handle much differently than it will with 29er wheels and the pedals will be lower to the ground than what you're used to.

You'd most likely be MUCH better off buying wheels that closely match those that came on your 29er instead of fooling around with 26er wheels.
