2 x .15 = .3000 -- 2 8mm perfs to 1 16mm perf.
.2994 is only a tiny bit closer than .3000 -- .0006" -- but that does
matter in printing.

But the lack of reversal print stocks (ideally, ECO in this case)
makes this messy and you face either significant generation loss of
the pain of working from a negative rather than positive.
I'd work from the originals, and just be careful. Film needn't be
damaged -- priceless originals are optically printed all the time.
Keep the gate and machine clean, and be careful.

Not if the lens is good. Contrast may increase, and if the lamphouse
is specular grain may appear to be increased. But go optical -- try it.
