That sound perfectly fine. I moved a LOT of my plants to hanging baskets this summer since 'footprint' space is not in abundance and I bring way too many plants inside for winter. I also combined a lot of plants like you did for the same reason. In the last pic I posted, there's a Monstera on a wood pole (board) with 3 kind of Pothos cuttings and some rhizomatous Begonias added a few months ago when repotted. I also started using the sides of the hanging pots by poking holes in them and sticking cuttings in the holes, which has been going well, lots of fun.
Something like Philodendron or Pothos that has stems that eventually get much larger in diameter would not be as good candidates for the sides of pots, should someone be interested, but great for the "growing out of the top" part. I don't intend for any of these pots to have much longevity, nor will I insist that the combos will always be the same, since repotting will be necessary in a year, two tops. So at that point, all of the stuff growing out of the side holes will be turned into new cuttings to 'start over.'
