I haven't tried it and am afk rn but I'd imagine you just define a constexpr function that implements collatz and use that in your contract.
(Edit: if the input is constexpr itself)
Its also quire easy to think about specializing a few templates and doing it that way. If you look up an example of the fib sequence in c++ templates you'll get the general idea.
