Compression Post?

I own an Ajax 28 and would like to install a compression post beneath the deck-stepped mast. Unfortunately, my boat does not have a strongback supporting the roof loads, nor longitudinal and transverse stringers providing rigidity above the bolt-on lead keel. My main bulkhead is nicely tabbed to the hull but not tabbed to the roof (or a strongback). This bulkhead simply slides into a groove moulded into the roof liner. Given these design details, would a compression post on its own transfer mast loads effectively from the cabin roof to the keel? In deck-stepped designs does the downward force of the mast need to be spread eveningly over the cabinroof/strongback/bulkhead/hull structure (that I am missing) or can it be simply transferred to the keelbolts via a compression post? Would point-loading the hull at the keel cause the shroud tension to banana the hull?
Thanks in advance!
