The 265/30 + 295/30 is perfectly fine as well, but the shoulder profile won't quite match, and the rake is a bit tall (about .8, depending on the tire, of course) because of the taller sidewall. And with said taller sidewall, if the owner doesn't plan to drop the car, then the front to rear tire gap that's already bad will only get visually worse.

Agreed. We discussed many of the different tire possibilities in our
M2C discussion thread we referenced above. While a staggered 265/30-19 front, 285/30-19 rear is desirable for the reasons you mentioned, lack of tire availability in that rear tire size can push many enthusiasts (especially track enthusiasts) to the 295/30-19 where there are more performance-oriented compounds available.
We had access to the 265/295 R888R, and since many of our customers are in pursuit of r-compounds for HPDE's, we thought we would examine and share that configuration. We also really like the Michelin PS4S as a performance street tire, but unfortunately, they are not available in 285/30-19 either. There is a lot more support from tire manufacturers in a 19" diameter than there used to be, so we're hoping more good options become available.
For reference, I've pasted the tire list from that thread below.

EDIT: I should also mention, Bridgestone RE-71Rs is a very popular Extreme Summer Tire among track enthusiasts, and they can be ran in 255/35-19 front, 275/35-19 rear.
