If you want my opinion, I can't imagine why in the world you'd want to do this. I have 26" bikes, 650b bikes and 700c bikes, but I rarely ride anything but the 26" bikes. They are just better in every possible way... except perhaps aesthetics... to some people, but not me. (I'm speaking of road bikes, not mountain bikes, where the bigger wheels actually do have an advantage.) I agree that it won't materially affect your handling. In most cases, what it will do is simply limit the size of the tire you can fit, so that you basically have the same overall diameter wheel but have to deal with harsher-riding, more-inflated tires as a result. And your braking power will be reduced, because you have less leverage at the brake arm. (At least for cantis.) If by some chance you CAN fit a taller overall wheel, you'll have a higher bottom bracket and higher center of gravity and reduced stand-over clearance - all of which are negatives to my way of thinking - but especially on a loaded touring bike. You have fewer tire choices in 650b than 26". If you have 135mm rear end spacing and QR dropouts, high-end 26" wheels are relatively easy to find on the second hand market (or in bike coops/shops, if you're on tour) because they dominated the mountain bike market for so long. Finding good, im-brake 650b rims/wheels is already a challenge.
