This mod introduces a lot of amazing concepts, from digging out a construction site for a building to taking time in the construction of a building to making resources without the need for ores. the last of those three is a very popular idea among mods, but most don't do it well without making it impractical, too easy, or lacking any realism. would it possible for you to make a mod with a building similar to this mod's rocket silo, but cycles between stages 1,2, and 3 as a sort of infinite miner that byproduces a lot of sand/stone/slag and sometimes needs support materials to go deeper?

Yes it is possible. Currently my free time is being consumend by my new mod MSI2. After that, maybe, why not =)
