Some of them would require more than just that.
Together these guys form a pretty strong skirmish force, but they apart from the dragoons and together with the other forces I have underway these guys help to flesh out regiments for the divisional level of play. Especially cossacks are required since Polish division needs to have minimum of two Polish cavalry regiments. There is some leeway whether they are basic, light or elite, Lithuanian or Polish, but cossack cavalry is required in all. They can have as support dragoons, infantry or western type cavalry regiments and divisional companies in relation to the amount of regiments (max five).
Getting to the divisional level will probably take time, so there is strong temptation to just push on in gettin more units into recognizable colors at the same time and leave final basing and finishing to one big final effort. However, since I will probably need to look at these fellows of skirmish play for longish period I try to get them into shape that does not hurt my eyes before the New Year.
