There is a very interesting debate going on where to get very good feedback. Thank you guys for your active participation.
We are covering a lot of topics, but they are still on track as far as the main issue is concerned.
There will be people who do not share this idea (we're here to discuss), but as I said before (see also the reference that appears in the devblog) I'm more willing to "redirect" the recruitment of noble units. For me certainly the recruitment of such units should be done in cities and I think that this function could be carried out by a Constable (petty nobility, see as the right hand of the Governor). I think that one in each city would be enough.
It makes more sense to me that for the recruitment of units belonging to the regular army bulk, be the headman, landowner, artisan, merchant, and gang leader who perform this function.
The constable could be in charge of supplying noble units, but also of complementing the quotas with mercenary units (the same ones we can find in the tavern - a shortcut). This character, like the rest of the notables, would provide missions which would be interesting to engage in activities such as bounty hunting, instruction, payment of commissions...etc (I'm just imagining)
