No. I never proposed for sponsors to be able to do that. The sponsors should only be able to sponsor the army and that's it. It is enough that their names are mentioned in every battle. Leaders of armies get chosen differently, either through election or appointment, depending on the government system.
Sponsors appoint the marshals of their armies, at will and with the ability to replace one at any time. Changing that would mean taking away most of the sponsor's power.
