Why bother even using 5E then if you're going to use a previous edition's adventures? Even if you didn't have to redo all the encounters from scratch and redo all the treasure, redo all the traps, redo all the DCs, basically remake absolutely everything in the adventure besides the maps, character backgrounds and descriptions, why even bother with 5E at all?
story is story. Edition is irrelevant to me. I'd prefer all the statblocks 5e but it's not necessary, but more work. And I like 5e.
