Adrian,
Because of the use of the leather covered standard boss, I'm not sure an alternative cowl would work. The stainless stalks would look good though although don't you use one of the wiper functions?
Why not make one or modify another same as yours, or have a chat with Mathias at MK, I bet he has something in his bag. Also I am pretty sure he does the stainless stalks for later cars. Alternatively Parks DE do modify stalks to make them stainless. My stalks are wiper on left and indicator right with flasher and horn. See you soon.
