Replying to Considering 50/50 Backcountry Setup - Got Questions

I'm a skiing addict. Skied 43 days at the resort this year before the covid-19 outbreak. Been thinking about getting into back country. Did a tour yesterday with a friend. Rented a little jig (called a daymaker) that lets you use your alpine boots and lets it pivot then you remove the jig and ski down in your normal alpine bindings. Worked pretty dang well but obviously a heaver setup.

I was thinking if I got into backcountry that I would go all out and get a setup I enjoy. I'm an advanced skier.
Been eyeing the Black Crows Nocta as a 50/50 deep day front side powder ski and backcountry ski. Was looking at putting the shift s/lab binding on it so I could use it with alpine boots on the frontside and ski it like an alpine binding on the way down in the back country. Therein lies the problem.
I love my alpine boots. They were fit really well and quite snug by an excellent boot fitter and they give me a lot of control. I hear that touring boots are usually a size larger to give you more room for the uphill. So wouldn't that mean I couldn't use my alpine and touring boots both with the shift because they would have to be mounted for one or the other? So seems like I'd be stuck using the touring boots on deep powder days. At a size larger I know for sure that would annoy me. I'm definitely used to a lot of control over my skis because of a snug fit in my boots.

How do other people handle this situation? Is it really a problem to tour in a snug boot? Maybe just get a few more punches than normal?

Thanks
