There's no such thing as two stage coming of Christ and the concept of one stage coming of Christ is also overrated. There's a billion things against your position and i don't know where to start but let me tackle the issue on second coming of Christ.
Christ doesn't come physically but as the kingdom of God which doesn’t come at a definite time- the reason He is referred to as “..He is and was and is to come the Almighty…”. Meaning that immediately after His death and resurrection, Christ comes back as the holy spirit and indwells believers (starting with the disciples). So, this kingdom of God has always been here with believers being added one by one until the end of the age. It doesn’t come with physical signs so that people can say “look, there it is, or here, come see it..” it is always in your midst.
Luke 17: 20Once, on being asked by the Pharisees when the kingdom of God would come, Jesus replied, “The coming of the kingdom of God is not something that can be observed, 21nor will people say, ‘Here it is,’ or ‘There it is,’ because the kingdom of God is in your midst.”[SUP]c[/SUP]
22Then he said to his disciples, “The time is coming when you will long to see one of the days of the Son of Man, but you will not see it. 23People will tell you, ‘There he is!’ or ‘Here he is!’ Do not go running off after them. 24For the Son of Man in his day[SUP]d[/SUP] will be like the lightning, which flashes and lights up the sky from one end to the other. 25But first he must suffer many things and be rejected by this generation.
Mark 9:1Then Jesus said to them, “Truly I tell you, there are some standing here who will not taste death until they see the kingdom of God arrive with power.”
Matthew 16:28 Truly I tell you, some who are standing here will not taste death until they see the Son of Man coming in His kingdom."
Matt 26: 63But Jesus remained silent. Then the high priest said to Him, “I charge You under oath by the living God: Tell us if You arethe Christ, the Son of God.” 64“You have said it yourself,” Jesus answered. “But I say to all of you, from now on you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven.”
Really, Jesus comes back as the kingdom and there’s no specific time.

One major error in your reply is that Christ and the Holy Spirit are one of the same. If that was true it would make Christs Baptism and John the Baptists testimony nonsensical. The same goes for Christs promise to his Disciples that he would send another comforter that would lead them into all truth if he and the Holy Spirit were exactly the same. Do you believe in the Trinity?
Like many subjects in the Bible the Kingdom of Heaven has a number of different levels of interpretation and a study of the whole Bible is necessary to fully understand it.
