I'd gone a bit further with that, I had the larger Tioga panniers and removed the 'stiffener' and hooks, bought some plywood and cut to fit, covered the edges with tape, installed inside the bag and bolted in, covered those bolt heads with epoxy so that they couldn't come loose nor scratch anything (like my hand reaching into a pannier). As for the hooks I hunted around for some aftermarket stuff, there's plenty around if you look on bag manufacturer websites, settled on some Superhooks as used by Wilderness Equipment (now Sea to Summit, or something), got them from the local outdoors store (had to order though), bolted those on. For the bottom hook I just used a picture frame hook but sourced some better bungee cord for it, once bolted through to that plywood backing it worked well. Enjoy.
If you don't want to go this far then you can always tackle the problem from the other direction: if your rack is thin then a bit of tubing placed over where the hooks mount might work, maybe a bit of garden hose taped down? I've seen this work. However replacing the stiffener in your bags with something that's actually stiff will help a lot with keeping the bags out of your spokes.
