cassette interchangability (if that’s a word !)

I’m running SRAM Force CX1 on my cross bike but want to change the gearing to a closer range with fewer, large steps. At present I have a 42 up front and 11-36 at the back. SRAM 11 speed cassettes are a little more expensive than Shimano, so any idea if I can swop out and use an 11 speed 105 which is about £10 cheaper and also more widely available. I’ll be swopping out the front chain ring also, have gone with narrow wide from Superstar
