It may sound like I'm just playing with definitions, but think of it in context. When you're a single person hanging out with someone else's (monogamous) partner, they are likely feeling concerned if you start spending a lot of time as friends together. It is also likely that when you're not around, your friend's partner is going to be asking a lot of questions about why you're such good friends and where it's leading. Even if you promise that it's just friendship, there's likely to be some insecurity and jealousy. So making it explicitly "platonic polyamory" would hopefully resolve the tension of monogamous expectations and fears. Especially if the couple you were dealing with already had an open relationship, it would be that much less problem for you to develop a strong friendship, don't you think?
Platonic love is non-sexual and non-romantic. Since polyamory is being open to or cultivating more than one romantic relationship (ethically, of course), I don't understand this "platonic polyamory" you're defining.
In the scenario you've given, I'm sure that making words up to describe the friendship one person has with another is really only going to confuse their partner and create more tension and suspicion in what is already an unhealthy hypothetical situation.
