Shifts are somewhat annoying to adjust to different boots, so if you plan on using in bounds ideally you have some sort of crossover boot as opposed to a dedicated touring boot + a dedicated alpine boot unless you don't need to change forward pressure at all to switch between. I (personally) mostly tour on my shifts and thus use a tecnica zero g tour pro because it fits my foot, can drive a real ski / binding, but is also super light. If I was using the ski in bounds on this set up all the time though and hammering bumps and stuff I would get a "real" boot like a cochise and hope my touring buddies were also on heavy set ups.
Go to a real bootfitter, tell them what you plan on using the set up for, and go from there.
