No, that's impossible. The language which describes the two witnesses of Revelation 11 is describing the role of the high priests who were the only ones who were able to "stand before the Lord" in the most holy place. In the post-exilic temple, God limited that high priesthood role to only the family of Zadok who had remained faithful during the exile period. Ezekiel 44:15 describes how the sons of Zadok would be the only ones allowed to "come near to me to minister unto me, and they shall stand before me to offer unto me the fat and the blood, saith the Lord God."
In Revelation 11:4, just as in Zechariah 4:14, the two witnesses are called "the two olive trees, and the two candlesticks standing before the God of the earth." This is reflective of the menorah lampstand in the OT temple, lighting the entrance to the Most Holy Place, where only the high priests were allowed admittance once a year.
There are no high priests that have existed since the AD 70 era. Therefore, this Revelation 11:3-14 prophecy had to have taken place while there were still high priests around in Jerusalem to perform those actions described in Revelation 11.
The two witnesses of Revelation were the two former high priests Ananus ben Annas and Joshua ben Gamaliel who were murdered in the streets of Jerusalem by the invading Idumean army in AD 67/68, aided by the Zealots inside the city who hated and opposed Ananus and those loyal to him governing of the city. Josephus records that a great storm and an earthquake took place that night, just as Revelation 11:13 mentions, and at least that number of 7,000 men slain, including the two former high priests. These two were left unburied in the streets of Jerusalem with their enemies rejoicing by standing on their dead bodies making jokes about both high priests' earnest exhortations while trying to keep order in Jerusalem.
The idea that believers in Jesus, both Jewish and Gentile, is repetitive in Revelation. See below:
“and from Jesus Christ, who is the faithful witness, the firstborn from the dead, and the ruler of the kings of the earth. To him who loves us and has freed us from our sins by his blood, and has made us to be
a kingdom and priests to serve his God and Father—to him be glory and power for ever and ever! Amen.”
Revelation 1:5-6 NIV
“And they sang a new song, saying: “You are worthy to take the scroll and to open its seals, because you were slain, and with your blood you purchased for God persons from every tribe and language and people and nation. You have made them to be a
kingdom and priests to serve our God, and they will reign on the earth.””
Revelation 5:9-10 NIV
“Blessed and holy are those who share in the first resurrection. The second death has no power over them, but they will be
priests of God and of Christ and will
reign with him for a thousand years.”
Revelation 20:6 NIV
The Two Witnesses are what the Bible says they are, not what our eschatological perspective says they are.
“Now if you obey me fully and keep my covenant, then out of all nations you will be my treasured possession. Although the whole earth is mine, you will be for me a
kingdom of priests and a holy nation.’ These are the words you are to speak to the Israelites.””
Exodus 19:5-6 NIV
“But you are a chosen people, a
royal priesthood, a holy nation, God’s special possession, that you may declare the praises of him who called you out of darkness into his wonderful light. Once you were not a people, but now you are the people of God; once you had not received mercy, but now you have received mercy.”
1 Peter 2:9-10 NIV
