I ran my CX bike as a summer road bike this year, despite not having water bottle cage mounts.
I ran a zero degree 110mm stem compared to a +6 degree 90mm stem for cross. I also run the bars slightly angled up and with the hoods higher for cross.
Other changes include a front mech and a 53 tooth big ring. Works for me, works for a lot of CX pro’s like Tim Johnsson.
