I don't know how you would do that. The heathers would have to be tiny. The emerging'buds' of hostas are right at the top, so the only way to do that would be if you had a very big pot, and put a few round the edges, but the heathers would then be in the way of the emerging hostas in spring.
You'd be better potting the hostas up in plastic pots to put inside your nice pots. That way, you can remove them in autumn, and replace with other pots which have something else in them. Easy swap then.
