For PvP I think the answer will almost certainly be no. In a no-skill cap system it is simply too strong to have a fully powered player getting support from strong monsters as well.

As for monsters and PvE, I quote myself from the other thread:

It is possible to make tamables unable to attack players, but there are still issues even outside of PvP, with bardic skills and magery players are already so strong vs. monsters that we have to give monsters ridiculous stats and skills just to make it a challenge at all, unfortunately this then pigeon holes players into using provo, fields and summons. I don't know what the solution is, but probably tamable dragons won't help!
