I think this could be a fun house rule. I don't see how it would break the game in any way.
I think it is too much of a small scale operation though for a game that is more strategic in scope and not sure it needs to be included in the standard rules, but for an optional or house rule, why not?
I would say that on the 'land planes' phase, that bombers should not be allowed to land on the carriers - they can only be placed on the carriers on the non-combat movement phase.
