What is your opinion on polyamory?

I don't know much about it. I can only speculate.
If everyone consents and is happy, why not? People can do what they want so long as that's the case.

Could work for awhile, provided everyone has top notch communication skills, and deals well with jealousy and no one feels coerced in any way

Happy...?

Ask an alcoholic if they'd be happy to have a bottle of vodka.

They'd tell you "yes"

I have the sneaking suspicion that such a relationship only exists in hypotheticals though

It works well for some people and not at all for others.

My Girlfriend and I are considering Polyandry.
