Notice rather inactive modding forum? I really don't think it is worth for the trouble because this game just has very basic stuffs regarding mods.
Unless someone finally does brave, tiresome work called reverse-engineering-whole-engine, the modding FE/LH is just tiresome and tied to very basic, simple mods.
It's a circular argument.

The easier it is to use / distribute mods, the more people will be interested in mods, and then more people will make mods.
Therefore, if there are cost-effective means of increasing the use of mods, and their goal is to have mods extend the longevity of a title, then they should do it.
