I think the BFI has a 16mm copy of the Tavianis Good Morning Babylon, but I don’t know about Kaos. I’m sure I’ve seen both, but they are a hazy memory now. Kaos is available on DVD as a US import, so tracking down the UK distributor might be hard.

And, isn’t Mnouchkine’s Moliere rather long? It’s possible, but again it’s not obviously available from any of the usual sources. I’ll continue looking.
