Hmmm I can't say I agree entirely on that characterisation of how Varis saw Zenos.
The way in which he calls him a monster when discussing him with Elidibus suggests he saw him as something worse, and not merely a royal seeking power. What I think Varis could not fathom is Zenos's mindset - his desire to seek nothing but self-satisfaction, with no further, deeper reason or agenda behind his goals, but he clearly believed there was something ghastly about him.
I kind of agree with your assessment of Zenos otherwise, but I just find him bland. He shows no reaction to the newfound powers he's exhibiting as facets of the Resonance... he's just perpetually reminding everyone of how bored he is. Fine, to a point, but he better get to one, and fast, or people are going to grow even more bored of him in turn.
I don't really care that he's got no real depth to him, but they could at least make him more entertaining. I also still believe he is going to get more than he is bargaining for out of Zodiark. His is a case of true hubris and it looks like he's simply the fulcrum to bring Zodiark into the plot without the need for all the Rejoinings to be completed.

His father wasn't exaggerating when he called him a spoiled princeling, that's exactly what he is.
Yup. There's no confirmation Varis ever experimented upon him. Zenos is a thrill-seeker and would often take risks of his own accord to circumvent his limitations. Varis removed Aulus from the Imperial Court. At worst, I think he may have simply observed to see if anything interesting came out of the experiments under Zenos's auspice.
The sole reference to an experiment I am aware of came from Elidibus in the JP version, but it's not phrased in a way to suggest Zenos was experimented upon, but rather that the entire affair was an experiment. Varis only began resorting to technologies he had previously ruled out once pushed into war by Elidibus, with the express purpose of safeguarding Pureblood lives.

Zenos is an open book yet nothing pops out.
Which is why people are already more intrigued by his new "friend", than him - presumably someone who doesn't mind endangering both Primals, or deceiving Zenos in some manner. His plan, as it stands, is just an idle fancy. If he really is aiming to absorb Zodiark, he has no way of ensuring the WoL does the same with Hydaelyn, to give him the match he so desires, and I think it is a pity that SE did not have Elidibus play some 4D chess here by putting the idea in his mind to pursue Hydaelyn instead in order that Zenos could secure your compliance with his plan... depending on how they write Zodiark and any further surrounding lore up, that would leave open an avenue for truly becoming a WoD - just not necessarily with the full Ascian agenda in mind - and would open up some interesting scenarios.
