sorry to keep following you around on this <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
are you running a jib on the boat to start with? if not, change the forestay to something that joins a lot higher for the bow bridle. This does not need to be expensive. use 1/8 vectran or dyneema for the bottom and 5/32 for the top part and put eye splices in them. Cheaper by 10c a foot and don't need to swage them.
I love HTs and don't wanna see the hulls get crunched unnecessarily <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" />

Edit: however, if you aren't going to ever be double trapped and don't anticipate high wind and therefore high mainsheet tension then you might be alright.
