Its not in Floris yet, it might be in version 2.6 (we still need to create more scenes among other things). There is no eta for 2.6, but "months" until full release are expected. To be more precise on the Kit vs the OP - Lumos Outpost kit does not allow building villages or towns, it does not allow limitless creation of outposts either. It will enable the player to build and own 2 outposts of which he can upgrade 1 to a fort (castle with merchants) level. (Thats 2 outposts+1Fort overall.) For a true construction feeling, you would have to check out the mod "custom settlements", which is for Mount and Blade.
