Good question! As I see it, you can use stuff from the Andromeda and the Multiplayer within reason! Mostly because like this is supposed to be a fun time[sup]tm[/sup], so I don't want you guys to not be able to use the cool powers that you want to use! Though I don't want anything that doesn't make sense like you guys having Heleus Cluster gear or something!

For example, Tsoi is a Vanguard. One of his abilities is Charge even though Charge 'lore-wise' is a result of L-5 implants which aren't developed till around ME-2 times. I'm fudging that because he still uses an L-2 which we know grants enhanced biotic ability as compared to a standard human biotic. Kaiden's ability being described as closer to an asari in terms of biotic power level units or whatever they use to measure how powerful your space magic is. Also in the comic about Kaiden's backstory, he basically does a biotic charge dropkick to crush Vyrnnus's brain so like I see that as precedent lmao. So like as long as you can make the justification on why you have said power if, I see a problem and ask, then we are good! Oh and of course engineers shouldn't be using biotics and adepts and vanguards shouldn't be making drones, but I'd like to think that that one is pretty obvious lol.
