Why? I'd expect all that water to rot armeniacum. If you just mean in a large, shallow tray.....Yes, I agree. The best grown micranthums and armeniacums I've seen were grown in large, shallow trays; or large hanging baskets.
Yes, thought was simply for large hanging tray like the pics posted of big baskets of armeniacum. ... Though they do require more water that way, definitely less than for Besseae.
I had tried to come up with a similar solution to the climbing bess syndrome and auto watering to mimic the environment by using something like a paint roller tray with a water pump in bottom piping up to top for trickling. Tray seemed too small though it has a slant and progress stalled if your tray were solid and you could catch water at bottom of slant somehow and pump up to top, you'd have something very similar to nature (and you wouldn't have to water every day )
