Axis response to a Mosquito-mounted bouncing bomb

What would the Axis response have been if Britain used a Mosquito-mounted bouncing bomb against German battleships?

Success would force reactions; Italy has more capital ships exposed, while Germany would likely shelter its surface fleet even more.

The Axis response would depend on Britain first making the weapon work and demonstrating success with it. Italy would have particular reason for concern because it had more battleships to lose. Germany would gain another incentive to shelter major ships in fjords and preserve a fleet-in-being. By the expected service period, large surface units were already a low German funding priority. A later clarification distinguishes German work on a rocket-assisted bouncing bomb from having an operational weapon.
