I "get" the desire to use Henchmen. I started the thread on Grimwell, after all.
There is a difference, though: Grimwell gives access to Nurses, who have great condition control and there is no other way to fit them in with our Grimwell list unless you use Grimwell as your leader. Alan gives great conditions, but Agent 46 might be the better choice for henchmen in that group since it means you'll have access to Doppelgangers, which are great in a variety of situations and difficult to counter given they can do the same thing other things can do, but better in most cases.
However, let's not cheat the question. Though you could toss out enough Slows with Doppelganger/46 and Alan to choke a horse, by taking Alan and 46 you can toss it out a max of 5 times. Not bad, but still less than the 7 you can toss out if 46 were your leader.
This limits your in-keyword henchmen to 46/Greed/Grimwell, which I happen to love in combination, but would mean you're essentially running the Grimwell list minus the Nurse condition control and healing. So let's leave it just as Agent 46 so you can play up Alan's strengths.
For Enforcers, you have a ton of points: You're going to take the Steward for scheme running. He's just too good not to in this list. He'll be out there dealing with your enemies scheme runners, or dying and taking out their scheme runner.
That leaves you with 35 stones. You could go Rider + Peacekeeper + Effigy of Fate so that you have 3 absolutely brutal beatsticks on the board. Might protect Alan, since it's going to be hard to let those guys free and 46 has Stealth. You'd also have 12 stones left, which means you could get Undercover Reporter for a hilariously trolly first turn if your opponent is unprepared. You would be really unprepared for Conditions list, though.
What were you thinking for a list?
