Putting some flair on my xenarite admech kill team

I’ve recently got into kill team, and since I also got easy access to a resin 3d printer I wanted to print some admech, but as xenarites.
My problem is that I don’t exactly know how to go about adding the details that would separate xenarites from regular admech.
I got a few ideas for now, putting skorpekh blades on a sicarian ruststalker assassin and giving a Tau pulse carabine with a mechanicus symbol on my skitarii rangers.
Maybe get some tau backpacks? Give the leader an Ork shoota for some comedic effect? Some more Necron weapons? Give one of the minis a canoptek scarab and say that he hacked it?
If you have any recommendations feel free to share! I want to be able to make a cool team so giving them some personality is essential.
