So I managed to convince myself that giving up actions to followers probably could work (with the notable caveat of free follower movement). And if this seems like a fun combat to me after a few hours of thinking about it, then I imagine the designers could come up with a whole bunch more that I like. Of course, I haven't figured out how to run the Valkyries that Odin summons on his next turn...
I think it's relatively easy to convince yourself that animal followers need direction to do more than just "follow their instincts." The same should be true of "mindless" undead, like zombies and skeletons.
One thought would be that you direct your followers as a standard action, meaning that you lose your attack action, but not your movement. The followers of course, still get to move.
The trick is that multiple followers (if you have them) should act in consistent ways. Freke and Gere (or any other set of animals or undead) behaving as a group and working together is totally believable. As a group, they get 1 action. Yes, you'd need to have stats for how the attack resolves when you have one wolf versus two wolves vs. three or more. But that's merely a matter of scaling powers.
Valkyries should be treated as Odin's allies. In other words, if Odin summons Valkyries to his aid, you should get XP for those Valkyries. Alternatively, if it's a daily power (for a PC), it's not that much of a headache.
Personally, I'd rather see followers and companions that actually help out rather than hordes of useless minions.
Minor thought: as minions, summons are pretty easy to adjudicate. You call them up and send them against an opponent. If it takes one action per summon, you'd be limited in how many would enter a fight. For example:
Summoning: As a standard action, you may summon 1 creature, mob or swarm. A creature, mob or swarm you summon is considered "controlled" by you.
Controlled Creatures: As a standard action, you may order a controlled creature to perform an action. Changing the action requires you to expend a standard action. You may have controlled creatures due to summoning, enchantment, or various other methods.
The theory is that if it takes a round to acquire the extra action, then a round to give them direction, you are essentially sacrificing two attacks to get your follower. Many players might do that once per encounter, but they'd be unlikely to do it constantly. Only a dedicated summoner would do so.
That's the general idea, any way. Balancing it would take time.
