Stupid question 2.0

[The Lizard King]

Ok, this should be the right section to post this.
I have this problem and I need some help: would it be possible to modify a pre-existing skirmish map so that my Terran structures produce units with the Armory/Tech Tree uprades from the Campaign? I'm new to the GE and would like to know how an expert modder would solve this little thing.
Have a nice day everybody!

Yes, you need to add the campaign mods to the dependiencies of your map, then you need to make all the campaign upgrades researchable in buildings (like normal upgrades are).
