I don't know why Riot still hasn't implemented that. Because right now I don't feel the need in buying multiple Skins. I just own one skin for the weapons I like and go on with them. However if there would be a option to select random skins...

if you remember Killjoy line "You can trust my bots. They only malfunctioned that one time and honestly, she won't miss that finger" it would be intresting for a new agent to be the one with the cutted finger.

Choose ur own 3 abilities for them and ult. An example and my own choice would be, Raze nades, jett smokes, and prob yoru or skye flash, with yoru or reyna ult. And make it reasonable like something that would realistically be added
