I see nothing wrong withj it , just go some where on The Bike
I think the inner 64 will take a 22T .. Still whole cranks are cheaper than all 3 chainrings at Retail.
Sell the one you have (or strip the 3 rings off the new one ) and sell the other with the current parts on It.
Modern cassettes fit a 12 or 11t cogs cannot push the market backwards
you can always set the Hi Limit screw to Block that one .
maybe you can find a 12-36
