Seen that this is the PM forum I don't think it is the best place to ask for a load order without ProMods xD
Anyway... The mod loading order should be the same, as the principal is, the mod on top loads at the end, and the ones at the bottom are the first to load. You just have to figure out which maps overwrite sectors from which maps and place the ones that overwrite with new content above the ones with the old content.
The load order should be the same as with PM but without the PM packages
