Surely Hasbro is the first one who wants a new videogame like BG3 but this needs a right team, time and money. I have said a DS videogame would be a survival style "Conan Exiles with psionic powers".
* Maybe no-halflings could survive the cleasing war because they could travel to other worlds...
Can we use the tag "Hyborian-punk"? Because this setting is like a mixture of Mad Max and Conan the barbarian.
We could create an "Athasian" version of other setting, and here we could enjoy total creative freedom to add and remove things as we please but I suspect one of the key elements are...
Let's remember the action-live serie "Once Time Upon" what was a complete reimagination of Disney tales.
A mash-up setting may need a new geography of the continents starting completely from zero. Really it would be more like a spiritual succesor of both previous franchises. We shouldn't worry...
The alternate Dragonlance timeline "Istar triumphant" based in the short story "There Is Another Shore, You Know, Upon the Other Side" allows a lot of changes to be closer to the DS style. For example if the gods of magic lost their divine powers then the consequences would be serious. Now the...
OK, I have got an idea of how to create a right Dark Sun version of Dragonlance. We start with an alternate timeline, explained better in the short story "There Is Another Shore, You Know, Upon the Other Side"

In this alternate timeline… the Kingpriest...
If we talk about a serie I would advice animation but if it is only a short trailer then it shouldn't be too expensive to produce. I imagine DS animation with a style like the movie "Heavy Metal".
At least in the dead-land there were two or tree undead lords as possible future antagonist leaders.
I don't mind the official canon but in my game there are worship to the ancestors and the totem spirits. It would be interesting if a character dies and she is offered to be reincarnated but it...
The Prism Pentad in TV? Possible but I would bet for the animation with PG13, or at least two versions, PG13 and PG16. I guess it would be after Hasbro had enough experience producing adaptation of its franchises.
The idea of mixing two official settings could sound crazy but if you don't feel...
