This is an especially important point to consider, especially back when Master mode first came out.
Many users were upset that Master mode was just extra stats and not even more overhauled AI, because they were used to it in modded Terraria, and some even said they should have just reached out...
people will accept any story as long as it is presented correctly. as long as its decently written and consistent, it'll be fine.
this is probably non-advice? but basically, my opinion - shoot for the stars and go for it
