Since your boat had a keel-stepped mast, I would have thought your boat had an aluminum casting with a flange to reinforce the hole in deck and distribute the side loads from your original mast partners. If not, the Tiara folks may have molded a lip to catch the mast boot, in either case they must have factored in lateral loads on your coachroof.
If you bolt your deck-stepped mast to the deck (via your sandwich?) you might check to make sure your coachroof is securely attached to a bulkhead near the mast or that the compression/jack post is securely bolted to the original mast step. As indicated in an earlier post, there is the possibility of the coachroof lifting if it isn't otherwise constrained. My boat (keel-stepped) has a SS stay that connects to a through-bolted padeye on my cast aluminum flange (on deck) at one end and to a bulkhead that is just behind the mast at the other end.
I'd also make sure the original hole in the coachroof is properly waterproofed if you have internal halyards. And then there are the electrical penetrations and cleaning up the old mast step.
It sure looks like your are going to a lot of effort to convert your rig!
It sounds like you are going through a lot of effort to convert to the deck-stepped configuration. You must have a strong feeling about this!
