I think it could be done with enough rock work, having your tank planted, and multiple feeding stations. I'm planning to try something like this in the future. The tank will be established, I will be raising my own food including mysis, and I plan to have multiple feeding stations on top of that. I say give it a go, just plan carefully. These guys are always in demand so if it doesn't work out rehoming the ones you need to shouldn't be a problem.
When you realize it won't work, it's usually too late because the fish has turned up missing because it's starved to death.
