Obviously ill need maps, would it be easier to make my own or to string a few together with rewards?

Never saw this term came up before, can you explain what's a "skirmish campaign"? Are you trying to run tournaments? Are you trying to design your own campaign?

more of make a campian like a video game, you could have a hero like darth vader of deployment gaarkan but what would it take to make a bunch of missions like that?

Should i just string together a bunch of missions and add rewards?

the campaign, is already a campaign. but you could use skirmish missions as prequels to events in your story. have it about an away team that had to infiltrate the ISB headquarters, you could have skirmish armies built around using units that would fit in the map.

or you could choose one army (rebels) and select 3-4 skirmish maps that could make a sequential story, based on the location or mission type, have a different enemy army for each mission (scum, imperial), then join up each mission with a bit of narrative between.

maybe you get bonuses like draw more command cards at the beginning of the match or start with an exhausted deployment. the balance would be all over the place. but you could try anything really.

How about a you are imperial or rebel, then you could have radom scum units that could fire on you or your ally like in one of luke's missions? we would need stuff like that but it would need to be different. trigers would also be nice.
