    as long as you keep the difference to no more than 16t you should be fine.

    Not a Shimano man myself, but I was always under the impression that from the 9000 series, the one crankset would take standard, semi-compact and compact chainrings.

    Here's your answer: https://bike.shimano.com/en-EU/product/component/duraace-r9100/FC-R9100.html

    Chain ring combination 55-42T; 54-42T; 53-39T; 52-36T; 50-34T;

    Yep. Completely supported. I have that crank in a 52x34, 52x36 and a 53x36. The only one officially supported by Shimano for optimal shifting (they have them shaped, pins etc.. to work in specific pairs) is 52x36... not that I could tell the difference between any of them in terms of shift quality.

    The obvious answer is a new bike!

    I think with 7 complete ones already along with a frame 2 group-sets and 3 spare sets of wheels that might be difficult to sell to Mrs Fowl.......
