The problem with your theory is that, though Peter quoted Joel regarding the reason for their speaking in languages, that part of the scripture listed above has yet to be fulfilled. He was just quoting, but there is no record of the above having taken place.
In addition, the above scripture is referring to the 6th seal, which means that prior to that, at the 4th seal, a fourth of the earths population would have had to have been killed. Also, if the 6th seal had taken place during Peter's time, then the world would have most surely experienced the trumpet and bowl judgments, which also have not take place.
All of these events of wrath are yet future, including Peter's quoting of the last part of Joel, which is the 6th seal. Your interpretation stems from not understanding the severity of God's coming wrath via the seals, trumpets and bowl judgments and that they are to take place in conjunction with Christ's literal return to the earth to end the age and the establishing of His literal kingdom on this earth.
