Imagine a giant's bow and arrow. Now inagine your mast as the arrow. Firing straight down. There's a lot of force there. I don't believe you could have a very effective post by making it removeable when not sailing.

Yes aluminum is not as strong as steel. But you could probably build a beam out of aluminum, which is about a third the weight of steel, and have it come out lighter by about 1/3.
Cabin tops are curved and this lends itself to laminated hardwood which would work well as long as the span was kept as small as possible. Look at this page at Northern Yacht Restoration for an idea. Northern Yacht Restoration | 1966 Pearson Triton Circe
