The Nameless, The Stalker, and Count Elithrion all have the ability to activate two individals/units. The Earl specifically can activate two units of the FB Militia, but those haven't been statted out yet.
I don't think activating two units of FB Swordsmen or other Individuals is a bad way to go, as there is precedent, and I would play it the same way as you and yours Morf.
It can be a powerful special ability if played right, or if initiative sets it up right, but I've seen too many games where it isn't spectacular either. It's still got the balance.
It is a very viable tactic to daisy chain command and activations, but you have to remember which one's got the higher LD!!
