Way too thin. The guillotine relies on weight rather than a sharp blade. You want more like 1/4" out even 3/8" steel plate — target weight is over a hundred pounds. You're probably also going to want 8mm rope — it's easier on the hands. You may also want to beef up the frame some, given the forces involved — both when the blade drops, but also because you're gonna have a couple folks hauling on that rope to get the blade up, possibly at an angle. Some kind of cheat so you can tie it off safely while it's up is important too. Workplace safety is still a thing, even during the revolution.

I'll grant the weight issue, but 3/8 is too blunt - it'll break a neck, surely, but I'm not sure it'll deliver that satisfying chopping action.
I'm assuming there's an optimum thickness that is sharp enough to cut but heavy enough to do so with confidence.
As a generally empirically-minded person I suggest we do a couple executions each with a number of different thickness and record the results. For science.
