Alternating taller and shorter hedging plants to save money

Hi there, I'm looking at cypress (goldcrest) hedging plants for quite a long run down the garden. I want height fairly quickly, but it's expensive to get taller plants of course. I'm thinking whether it would work to buy half of each height and alternate tall and short ones....is that just a crazy idea? Maybe not 1 tall/1short all the way along, as that will look too formal, but a bit more random. Is there something I'm not considering when thinking about this? I'm not fussed about having a very formal trimmed hedge btw.

P.s. I'm doing a native hedge somewhere else, so please don't suggest swapping out for this! I know native is better for the birds. But we want something evergreen and fairly quick/tall on this side as our neighbours cut down the whole established hedge and replaced with a 1m (!) fence, so we've lost all privacy.
