Re: How many transporter rooms on TOS Enterprise?
"...the mirror image of a putative corresponding room on the opposite (port?) side of the ship would in that case be a double mirror, and would thus have the same plan as the existing set. So at least two slightly different transporter rooms would now plausibly exist simultaneously, in a ship that would remain laterally symmetric. (That is, if lateral symmetry is found desirable...)"
I thought I had already visualized your idea (see post # 72): http://www.trekbbs.com/showthread.php?t=195496&page=5
Well, I definitely found the symmetry to be desirable.
