I think it is a delicious new frenemy ship. I did always imagine Jupiter being the slightly flirty type, even if the recipients happen to be someone on the other side who doesn't fall for her tricks.
... and to be honest, I really do see Jupiter/Looker as frenemies at the least, if only because the two of them were just talking so very casually despite the situation in the opening scene of DP150.
... But hey, we shippers like to take what we can get. XD
