[2023] Great new idea that will fix naval warfare, what do you think ?

The idea is to have specialised ground troops (lets call them sailors) with limited ground combat ability, but they are the only troops able to turn into all kinds of naval ships with actual naval combat ability. And make other troops like archers and swordsmen ...... , only able to turn into transport ships with limited naval combat ability, in order to transport them to enemie coasts while being protected by the actual navy (sailors). This will fix the problem of navies being too powerful compared to armies, and I also think archers being able to turn to battleships is unrealistic .
