So I was thinking of mixing Steel Legion and Cadians together, mostly because the Cadians are so much cheaper, and they come with the flamers and extra bits. What do people think about this? I was thinking of getting maybe 10 of those Pig Iron (?) heads with the gas masks. I also have spare heads such as Spase Marinez!! screaming heads, bionics, those Eldar Guardian heads with no helmet. Etc.
I think it should be fine so long as I lose the majority of the Cadian heads, the Steel Legion coats are not that long. They are not the wallowing in mud great coats that the Death Corps wear.
I am getting at least one box of Catachans, too. There are plenty of heads there. The conscripts can wear the helmets.
I will probably get at least one box of Hive Gangers from Necromunda. I want a variety so it does not look tired.
