It doesn't seem implausible for Connie, over the course of years, to have insinuated herself behind the scenes as a vocal presence in the Family.
I might agree if she were at Commission meetings or had a crew, but the only time she comes close to giving an order is when Michael is incapacitated and the Family is in disarray.
Again, this doesn't seem implausible to me.
