Dragonlance is such a mystery to me - it was probably the most well known setting at one point forty years ago, with the books making TSR considerable money. And they just kind of let it die on the vine. Ravenloft, amazingly, kept being nurtured and updated with virtually every edition of the game, and now it’s maybe the second most recognizable setting after Forgotten Realms.
How might have design decisions changed if Dragonlance was still one of their top settings? Would Draconians have replaced Dragonborn? Would orcs have been introduced narratively in some way?
The SAGA version and associated books I think did much to cool people's interest in DragonLance, I know it did so for me and that the game line associated with it did fairly awful.
Sovereign Press tried to keep the line alive, but they were a speck compared to WotC - and weren't getting any help from WotC for that matter.
Rolling it back to the War of the Lance for the latest book I think was their best idea to present it once again, especially with moving the action northward where that part of the war hadn't been explored and was open to let players use their own PCs.
It would need a blitz campaign on the level the original had to get a lot of eyes back on it, but with the D&D team's flailing to co-ordinate other media with releases (so many times it seems the right hand doesn't know what the left hand is doing) I don't have a sense it would be something they could handle without major changes in their team dynamic.
In short, they'd need to make a major push to energize Dragonlance, and these days these seem more fire & forget with products.

And I'm sorry, as much as I like Dragonborn, Draconians have no place as PC options during the War of the Lance. (After the War might make
some sense, with Takhisis's control over them severed, ala the freeing of Warforged in Eberron). And Draconians are Dragonlance's Orcs, they don't need to be added in.
