I ask this because i would love to see the Caliban in Lancer Tactics

Mecha RPG adapted from Lancer tabletop · By
From here:
Currently, only the content in the core rule book is on the production schedule as we aim to fulfill the Kickstarter obligations. After that we’ll be spending some number of months tightening things up for a steam release. Any expansions/modules past that will depend on how well the launch goes ++ conversations with the authors in question.
So: not yet, but maybe someday.
If I recall correctly; and by browsing the FAQs in the Kickstarter page that ended; I am PRETTY sure they're in favor on Steam Workshop being allowed/implemented/toggled on. They already have a map editor IN the current released most updated version ....so I'm not seeing why they'd not toss this into the Workshop.
