People will probably disagree with me but as you said, I’d play around with profiles long before I’d do a holder swap. There isn’t enough difference in size or amount of steel on the ice at any given time to justify it imo.
a good profiler could look at your current blades, get a general idea of the balance point and ice contact you like and get you something similar to what you’ve been using.
it will likely take longer to adjust to the boots than the blades anyway.
