Personally I'd say, ultimately, all that matters is that you tell a compelling story which:
A) Basically has the same/similar themes to the original.
B) Doesn't like, actively burn down the original unless that's very much the intention.
I absolutely get what you're saying but that is also going to make anyone who's a fan unhappy since unless they're there for the same/similar themes, it's going to just be "off."
There's definitely a spectrum where you have someone who's trying to do things "shot for shot" to line up with the text, and what basically amounts to bad fanfiction for the source. I think WoT heavily veered into fanfic territory, but I was a casual fan (I read the first two and a half books at first release and then noped out).
And also, the serious LotR fans still haven't forgiven it. I just had a conversation with one of them and the subject came up. I must admit I deliberately turned the conversation to the point where they said "Jackson should write his own books!" but then these were friends of mine and we were having a few beverages, so no (permanent) harm was caused and we all laughed it off in the end.
I don't have psychic or prophetic powers, but I think Dragonlance will have a lot of changes made to it to adapt it for modern audiences. Much like WoT I won't be too upset because it wasn't my thing at the time (due to some parts that I expect will get cut). I'm sure the purists will be upset. But will what remains be Dragonlance?
If I can give another example, I saw the Mario movie last weekend, which turned out was too scary for my daughter, so I saw some of it solo. I know a fair bit of Mario lore, and the movie updated things, but respected the fans and had many winks and nods to them. I think you can change many things if you're still showing the fans respect and put in enough easter eggs that they can chuckle at.
Will that be what happens? Hope so, but expect it to be something entirely forgettable, just like the animated movie was.
