Actually, the fact that nobody has implemented HTTP over UDP puts such a
constraint on you. Just because the RFC allows for it does not mean that
somebody has actually implemented it on both the server and client side.

I am no expert here, but there are probably much better ways to do this
using more recent and more sophisticated protocols.

When I was working for a company that shall not be named that was working
on edge routing solutions, one of the big things was QOS and priority
scheduling of "real-time" or streaming data. Unfortunately, my knowledge
here is barely superficial as I never had to get deep into the mechanics
of that to write my test software (which ran functional testing of various
high-speed ATM optical network interfaces).
