Sorry to be late to this thread. I taught advanced hobie sailing in the late 80's and early 90's and have spent many, many hours repairing hobie's for our fleet and as a side job for a a bunch of the private hobie owners. As someone said, Try to fix the problem at the source. we used to do this by pulling the whole tramp frame (with tramp on but loosened) assembly up and off the hulls. We would then shim the posts buy cutting aluminum cans in about 6" strips, fold them in half, the slide that shim over an edge of each post so that half the shim is inside the foam filled post and the other half is on the outside of the post. With a rubber mallet and a couple buddies, pound the frame back down onto the hulls. Tightens it right up.
You are right, that is a great way to do it. I did that with aluminum can shims last year. It was so tight, pounding the frame on, I was scared I was going to damage the pylon shoe connection to the hulls. This did stiffen it up a great amount, but It still felt there was still some amount of slop, but probably an acceptable amount. Add the mast/rigging weight, etc. to the boat and there it was more noticeable that there was still a bit of slop. I just wanted a rock solid connection between the joints. I will say the epoxy did stiffen it up a small amount more over the shims, but you will have to ask yourself if you want to have to heat up the connection with a torch to get them apart should something need replaced. Even with an epoxied frame, mast up, but rig not tensioned, if I lift a hull while on the trailer, there is still about a 1-1/2"-2" deviation before the other hull lifts. Aluminum can shims had around 2-1/2-3", and before any shims around 4". I know a tight tramp plays a big role in this tension as well.
