It would be impossible to put expanding 2 lb foam into that small area to I guess stop what you perceive as a weak area?? No it is not. Yes you can have what they call an oil can effect because both pieces are not extremely thick or cored. But as Bushwacker said and documented. No failures. Expanding foam would only cause probably the inside liner to bulge in different areas and look ugly. Yes there are many things that need improvement to the 1960s moseley hull. They used 20 inch engines back then but now all want 25 inch engines and the added safety height for water control. Also plywood was the only material available back then for transoms and floor. Now many of us are using coosa foam glass type high density material. If your boat gains any weight with water absorbtion of closed cell foam or plywood cores getting penetrated by water. Then the floor will be two low to self bail. Especially with new 4 stroke heavy engines. There are improvements that can be made but injecting 2 lb expanding foam into the liner void is not a good move.
