That is your opinion but in John 20:22 Jesus breathed on them and said: " Recieve the Holy Spirit". The risen Lord said this and He stayed with them 40 days, then after instructing the Disciples to go and wait for power from on High. They had the Holy Spirit in them when Jesus said to them "Recieve the Holy Spirit." in John 20:22. They confessed Jesus is Lord (Roman 10:9-10) and they believed and were saved. Just as we are today when we place our faith in the Risen Lord.
Luke 24:49 Jesus tell them to go and wait for something more Power from on high.
What more would one need? Jesus was with them for 40 days. In the Book of Acts chapter one, the context continues Jesus is speaking in Acts 1:8 "You shall receive power after the Holy Spirit has come upon you. to be a witness". They did not need the Holy Spirit to be saved at Pentecost, they were already saved. They were empowered as the Holy Spirit came upon them as the Holy Spirit did in the old testament call the Spirit of the Lord or Spirit of the living God. Same Holy Spirit but now The Holy Spirit abides with us as John chapter 14 states. Your suggestion of a special experience for the elite few is not what the word of God teaches. Jesus said in Luke 11:13 "If you then, being evil, know how to give good gifts to your children, how much more will your heavenly Father give the Holy Spirit to those who ask Him!”"
what are you asking for? The Holy Spirit comes to be in you as Jesus said in John chapter 14. You do not have to ask for what is given for salvation one just needs to place faith in the Lord Jesus Christ they will be saved and receive the Holy Spirit. The Holy Spirit does more than what some think He does. He is with us, in us, and comes upon us.
