Vertical Castling?

After doing some very light research, I learned the following:

• Prior to early 1970s, the FIDE rules did not specify that castling had to occur along the 1st rank (8th rank for Black).
• At least one person created a funny puzzle where White would "vertically castle" taking advantage of the technicality.
• FIDE then revised the rules to clarify castling along the 1st/8th ranks.

So it looks like it was technically legal to "vertically castle" prior to 50 years ago, but that incredibly niche possibility has passed.

I don't think this can be possible, because to castle neither pieces can be moved, because that makes it impossible to castle.

Rooks never start on the e file, this is impossible

If a pawn promotes on e8, then technically the rook would start from that square.  Hence, the "vertical castling" theory.  See my previous post in the thread to a link to the puzzle that kicked off the idea.

To vertically castle you would need to promote to a rook on the same file as your king then do it 

the theory behind vertical castling could be not just a loophole in the rules, but also the "birthing" of a rook; so when you make a rook on the king's file (when the king is unmoved), you could theoretically do vertical castling, but as soon as that rook moves to a different square, the same rules apply; no castling for that specific rook that was moved, or no castling rights when the king is checked and is forced to move elsewhere.
TLDR; vertical castling when the pawn promotes to rook on the king's file and default rook and castling rules apply.
