Stick on numbers will work at least for a while. As with sticking anything surface prep will make a big difference. Will potentially still cause permanent damage.
Common approach on Loch Lomond is a board that is just tied on. They often bounce around and end up invisible - but rangers don’t seem too bothered.
A better approach may be to fit some straps to the boat (the sort used to hold oars in place? Or just some extra d rings? Or industrial velcro?) and attach the board to them - anyone buying the boat who also needs to display numbers would see it as a bonus whilst they wouldn’t detract for those who don’t need them.
