If the A-class descide to allow "banana" boards there will be changes all over the boat until it has reached the same level of refinement as the current boats. Imagine the number of foil designs that needs to be tested combined with position and hull shape. The changes needed will make the boat even more expensive once it is stable, but the big problem is to convince the sailors to stay until things are stable again.
I doubt that you will be able to compete and top level with a modified boat. You will probably need to move the trunk and make reinforcements around the trunk since there will be other types of loads from the board.
The best thing is to have a ballot and check what the sailors in the class want. If they sailors thinks banana boards are ok I think we should concider another option, to remove the foil ban completely. The banana boards are using a loop hole in the rule, and it might be a more expensive solution than to have full freedom when designing foils.
