I've seen other posts here that the 40 tooth cog works fine with the K-Edge conversion but you will be getting bigger jumps in your gears.
Yeah we have a 50T big ring and an 11-34T cassette which gives us all we need for our flatish bunch ride in Group 2. 10sp cassette so the jumps are good. We never get off the big ring in that bunch and don't spin out on the run-in to the cafe @ 55kph if there is a tailwind and we are fit. We are both happy at 105+ RPM, bursts up to 120RPM no problem.
