Dying wandering trader to change trades

Just a suggestion but what if you could give wandering traders different colours/ items from the specific biome to change their types of trades? Obviously the default colour is a randomised trade selection like normal but say for example you had yellow dye or sand to give this trader a new selection of trades from the specific biome. So they could trade desert biome items with the players. This may be useful, and what if wandering traders also spawned out on sea? They could have boats with a chest behind them instead of their original llamas acquaintances, so if you give them a light blue dye they can become a ice biome trader, cyan would be for a normal ocean biome, and blue dye could be a tropical ocean biome. Obviously there would be more with each dye corresponding to that biome (eg: lime= valley, green= jungle) this could be useful in many ways to player as they could also trade wood blocks with players, via the player trading something like apples or flowers since they’re a common item. I would like to see this in bedrock and Java editions for minecraft.  Thanks to the Mojang company for such a wonderful childhood game, also sorry this was long.
