The arcospheres themselves aren't scripted; all that code related to arcospheres just creates the related recipes. So you can let the Space Exploration code run first, then change all the arcosphere recipes to use and output only the base arcosphere.
(Though really there should be two types of arcosphere, an "active" arcosphere and an "inactive" arcosphere, to preserve the quality that your arcospheres might be the wrong type and you need a separate machine running to change them to the right type. "Inactive" arcosphere can be the base arcosphere.)
