I went to school with a kid named Chr!stopher R0bin (fn/ln) and everyone i knew made the connection, but that was his full name. I think especially since your first is R0bin so it will be R0bin and Chr!stopher or R0bin and K!t it won’t be as noticeable, but people will probably make the connection
[name_f][/name_f]but i also think it’s a cute harmless thing, so as long as you don’t mind hearing “oh like winnie the pooh” a few times you’re fine
