No guarantee you will like either of those necks as much. A week isn't a ton of time for a guitar to settle into a different set of strings and a totally new climate. If you like it as much as you do, just play it for a while and keep adjusting it if you need to. No harm in being patient.
TBH, the thing that I like about this neck is the worn finish. The profile is good, but it's not unique to that guitar. It's just the Modern C. The frets are better than the Gibson (slightly larger), but that's not saying much. The frets on the Gibson are tiny.
If the neck is thinner, with a flatter fretboard, and bigger frets, I'm 100% sure I'll like it better even if the finish doesn't feel as nice. ESPECIALLY if it's stable and doesn't take days to "settle in".
However... the big part is I'm sure the neck is a huge percentage of why the guitar sounds like it does. Sooooo... if I change the neck, it's going to change. It can improve, but it can also make it worse. So it's that risk I'm worried about.
For me, a week is already pushing it, TBH. Or at least, it has been enough for my Gibson and my Epi and even my cheapie Squier. It's not like the weather changed. I trade it with a guy from the same city who also has heat at home. I don't know if his house is humidified, sure, but my house isn't, and my Gibson has had no trouble even during the change of season. Temeprature is particularly low? Sure, I need to loosen the truss rod a bit. But then, it stays like that for days if not weeks, not just hours. I mean, the Gibson's neck was also "used" to 10's as well when I bought it new, and I don't remember it taking DAYS to settle in.
