howdy!
I often play SWminis in "40k in 40mins/SW40K" mode, which is loosely based on KillTeam/SWRPG.
Imperial Assault Skirmish mode is also neat.
that has one-player mode also.
I recommend looking into "SWMinis via correspondence"/ FFRF's "bi-monthly boardgame livestreams",
tabletopsimulator, SWMplay's StarWars app framework,
VASSAL starwars, and
this thread by KezzaMachineII "SWM:AI...?
KezzaMachineII's rubrik is very similar to SAGARPG/Kill-Team lite.
I have photo-archival indexed variants on a google cloud if you can't get a hold of KezzaMachineII hehe.
the only difference for the random system, is to utilize the tabletopemulator APP to MCMC random the random-select hehe.
all of the Missions rulebooks and Deagostini rulebooks contain missions and scenarios,
as do the League kit inserts.
A proxy of those can be found at BoardGameGeek or at SW:Gamers.
I hope this is of use for you, and good luck gaming
(P.S. I trust we'll be seeing custom stats or dare I say custom miniatures for the VSet pieces over on the custom thread?
)
