Given that the only major change, afaik, needed to make these work in space is the addition of the se_allow_in_space = true tag, would it not be easier to simply set the original mod as a dependency and add the above tag to the relevant entities at the data-updates step, rather than replacing the original mod? Then you wouldn't have to worry about backporting updates from the original, nor deal with conflicts with the original due to mod dependency specifications (like the above modlist issue). That would also let you do all of those updates in a single mod, since you could simply switch off the mods[] list and conditionally add it to the fluid and logistics entities, if also installed.
