Just make sure the plastic container used is a snug fit in the apidea. I have people in the queen rearing group using plastic containers which reduce the capacity of the feeder by 50% or more. The bees will starve if you get a week of wet weather and the apidea is not checked.
I remember this happened a lot last year when the weather was bad. If you reduce the feeder capacity be prepared to check the apidea far more often - and that can be making extra work if the apideas are at a mating site somewhere.
