Let me see if I get it right:

1)OOB formations are not used in scenarios.
2)Editing picklists, you can replace anything with anything at your own risk, but without major bugs as far as I can tell. So where is every single formation in the formation list doesn't matter except for a few critical ones like the HQ.
In different picklists I have had infantry companies numbered 4, 6, 7, 31, 33, 37, 43, 98, 281, 437 and anything else, infantry cos replaced by commando platoons or mechanized formations and reverse...
It doesn't matter as long as you don't mind messing up the OOB and the picklists.
