I fear a repeat of the lost-opportunity that D:OS1 toolset brought -- a toolset that (almost) only a Larian developer could use that saw a grand total of (maybe) two(?) independent adventures/stories created 6 months or so after release?
The Adventure Creation toolset needs to be easy enough for a non-technical, non-script-expert, non-programmer to be able to create stories that don't require a live DM and can be shared with the ease of merely pushing a "publish" type button.
In retrospect, it was probably too much for us to expect modding tools that could allow one person to make a module on their own, when LARIAN doesn't have one person who could make a module on their own. Making a map in D:OS/2 is a team effort from Larian.
What you're asking for is not an easy thing in the slightest.
