It seems to me that if you send out an early probe (say, before your first pylon) you could steal both of your opponent's gas geysers before they would usually get one. You would have to delay your gateway until about 14 supply. But this should allow you to get warp gate much earlier than your opponent, as well as gas units like stalkers when it would be difficult for your opponent to get sentries to FF your units. This seems even more potent since in PvP, the mantra appears to be "Expand first, lose first"
So, the question is, is this a viable strategy? You could transition from this into a 3-gate-robo, or even into a 4-gate. Yet I have never seen this strategy used at a pro level of play. Is there any reason why this build order is bad? Additionally, what is the best way to counter a double gas steal, if, in fact, there is a very easy counter?

No it is not.
He would have a huge economical advantage, as you send out your probe so early and You invest in 2 gas without using them. But a good opponent would immediate take his second gas once he sees the gas steal to prevent this.
This way you are stuck with a really bad economy, he still can tech to Stalkers, add 1-2 gates and push you with his first units. You will have lost more than 150 minerals with your strategy.
But even if you steal both gas he can add more gates and push you with pure Zealots. Depending on your micro you can kite those with Stalkers, but as everything is delayed you will have too few units to be efficient. He will have 4 Zealots while you have 1 Stalker. 2 Zealots attack your probes and 2 chase the Stalker. Even if you can defend your economy will be screwed.
During this time your opponent will have either expanded or killed your 2 gas in his base.
This is if you opponent can cope with the situation and knows how to react. Up to gold or platinum league you might throw off your opponent because he does not know how to react and win.
