You might want to add more holes to the plate. Something about having air under sips is what's making them work so well, I'm not sure if it matters with wicks but the sip thread on another forum that's the theory, but I use wicks in plastic pots without any problems, go figure.
Whatever you do with this method it's easy to change things up, if it's not getting enough water you can add more wicks, to wet, remove one.
You can take the plants off of them if needed. I've had a few small roots attach to the wick but no problem,
If that's going to be outdoor you might need an overflow hole in the base about an inch below the wick plate in case of rain. Might be hard to do in stainless steel.
