re: " From my standpoint, still admitting I am not familiar with this '6th day' view..."
re: "...the crucifixion... occurred on Friday..."

You say you're not familiar with the idea of a 6th day of the week crucifixion. But then you go on to indicate that you are. What am I missing?

re: "...it is well established that the resurrection occurred on the first day of the week..."

There is only one verse (Mark 16:9) - as the KJV has it - that places the resurrection on the first day of the week. And that verse is by no means a slam dunk because many good study Bibles question whether the verse is authoritative or punctuated correctly.

re: "...the historic view of the crucifixion is that it occurred on Friday..."

Historic in the sense that that has been the majority opinion. But there are also historic opinions that the 6th day was not the day of the crucifixion.

re: "...your only choice would be to hold that the crucifixion actually occurred on Thursday.
Would that be your position?"

Yes, I think that the 5th day of the week is the more likely day, although I also think that the 4th day cannot absolutely be ruled out.

re: "1. IF that is correct, what would be its significance vs. the historic view?"

Other than negating the 6th day crucifixion view, it would mean that the Messiah was correct when He said that 3 nights would be involved.

re: "2. IF that is correct, who else besides yourself holds to this position?"

Below is a list of some Sabbath observing organizations of which most disagree with a 6th day of the week crucifixion.
