mechanical keyboard likers..... please help me.......

my ducky one 3 in bright yellow has taken a poop after 6 months. it is double-typing all over the place, seems to be a common issue, so i'll be warranty returning it and returning to my previous keyboard (ducky one 2). however, the bad keyboard came in the best colour in the world, a wonderful rich egg yolk yellow, and i am obsessed with it. keeping the keycaps and throwing out the defective keyboard is both money inefficient and tremendously wasteful....... but i can't find anywhere selling a set of these keycaps in my layout (ie get that bastard £ symbol off my keyboard). can anyone recommend a course of action 🥺
