>>The proper translation should reflect a continual state of being.<<

It does. He forever will continue "having been slain". Never again will He not "have been slain". That does NOT mean He is still being slain. If you have done something in the past it will forever continue to "have been done".

>>So the more proper translation (of the perfect tense) in verse 6 would use “being” instead of “been”.<<

No it wouldn't. Not any more then what you did in the past is still being done by you now.

>>to the (looking as if He is BEING slain) Lamb of God.<<

Wrong, Christ said "once for all. Christ today is BEING at the right hand of God.

Revelation 5:6 And between the throne and the four living creatures and among the elders I saw a Lamb standing, as though it had been slain, with seven horns and with seven eyes, which are the seven spirits of God sent out into all the earth.

Looking like it HAD BEEN slain.

And people don't seem to note that it was STANDING.

And you're right. It's not standing being slain. It's standing as though it had been slain.

When Jesus appeared to the disciples, He still had the marks of the Crucifixion on Him, the holes in His hands and His side, and yet He was very much resurrected and alive.

He was not in the process of being slain when He told Thomas to put his hands in the wounds. He HAD BEEN slain. Bearing the marks of past action to not indicate the action is continuing.
