zen nudist....I agree that the absence of the Holy Spirit in these visions could indeed be a problem, assuming that the Spirit should have been depicted (as it is in the synoptic depiction of Jesus' baptism, in which the Holy Spirit appears in bodily form). However, as for the distinction between the Son and the Father (as in Revelation 4-5), as I mentioned before this would not be a problem for trinitarian theology because the two are not "confused" with each other in the Trinity and are instead regarded as distinct persons and would thus presumably appear as such in merkebah visions. Their unity however is also also implicit elsewhere in Revelation. The "Lord God Almighty and the Lamb" together comprise the eschatological "Temple" (21:22), both the Father and the Lamb sit on the "Throne" (3:21, 7:17, 12:5, 22:3), salvation belongs only to "our God who sits on the Throne and his Lamb" (7:10), both the Lamb and the Lord God are called the First and the Last and the Alpha and the Omega (1:8, 17, 2:8, 21:6, 22:13; cf. Isaiah 41:4, 44:6, 48:12 which refer to Yahweh as the "First and the Last"), both the Lamb and the Lord God shine providing light in place of sunlight in New Jerusalem (21:23, 22:5), and so forth. Note also that the description of the Lamb in Revelation draws on the description of the Ancient of Days in Daniel and other OT scriptures referring to Yahweh (cf. "the hairs on his dead were white like wool, as white as snow," Revelation 1:14 = Daniel 7:9, "his voice was like the roar of many waters," Revelation 1:15 = Ezekiel 43:2), which is reflective of the overall pervasive pattern in the NT of applying to Jesus OT scriptures referring to Yahweh (cf. for instance Joel 2:32 = Romans 10:9-13, Isaiah 45:21-25 = Philippians 2:9-11, Jeremiah 17:10 = Revelation 2:18-23, etc.). Again, this is not at all intended to show trinitarianism is in the Bible per se (it is rather as much an artificial construct as all other harmonizing christologies), and rather I prefer to take each text on its own terms, but it is pretty hard to deny that many NT writers saw Jesus Christ in light of the "Lord God" of the OT. Along with the full-fledged deity ascribed to Christ in John, Colossians, and other texts, it does not seem reasonable to argue that a stated relationship between the Son and Father necessarily removes any basis for recognizing Jesus Christ as God.
