Gambling machine where all machines are running all the time?

I've looked at a few gambling machines and they all have a common issue, only 1 machine tends to have the ingredients to be running at once. This causes the whole process to be very slow and very wasteful of my high quality quality modules, which are in short supply whilst I get gambling running! Plus it's a waste of space which I'm in short supply of on Fulgora!

I've thrown together a setup which has all the machines running at once and switches as needed, but it feels a bit ugly put together with so many selectors and combinators. I was wondering if anyone has seen a machine which can do this and could share a blueprint?
