You are if you're considering a cypher that's extremely likely to be secure.

In this case we're ok to introduce something with a chance to be quantum-resistant before it's been studied enough, because we want a chance of being quantum-resistant soon.

But that's only ok if you add it to the existing, reliable, systems.

Were there not the issue of quantum computers we wouldn't even be considering to use different cyphers at this time.

It's "cipher". But we're not talking about ciphers; we're talking about key establishment algorithms.
