Is this a good idea?

Recently getting into the hobby again, went from roughly 15k points of necrons, now starting chaos - How do you guys think a warband of all mix & match chaos would look? I don’t intend to get into the gaming again (no buddies to play with, live too far from nearest shop). I’ve almost finished my thousand sons heldrake, but i do love the look of all the other legions. Open to suggestions & opinions on what ones to do next! Currently have 5 chosen, a sorcerer in terminator armour, and 20 legionnaires lined up.
