Brad,
As Odd as it may sound, an Optical preamp, Suitable 363 chassis, an MPU-1 and Q-SYS and you've pretty much lost the need for the CP65 or CP200. The Q-SYS will do format 43 (just set up the crossovers/summers and "snapshots." You could probably do away with the optical preamp and just use the Q-SYS mic in and, if need be, a loading resistor. Use up to three Dolby 363s for SR or A NR and again, setting up snap shots, you can have noise reduction on legacy formats. Certainly, the easy button is using a suitable cinema processor to decode "film" things.
The CP650 also lacked SR NR for 70mm (at least I don't think you could apply SR to 6-channels) and by the end of mag 70mm, it was all SR and mostly format 43 (that I ran).
I don't agree on using a D/A converter for DCinema. You've degraded the audio with your converter and then took another hit converting it right back and also gave up 2-channels of DCP (MOST movies are Surround 7.1 now and that costs near zero to implement). CP650s are just a film processor for me now. The few sites that have CP650s running DCinema were relatively early conversions for us, before we knew of Robosound and they all retained film so the CP650 made sense.
We just INSTALLED a CP650, in fact, to run film at one of the museums downtown. They have DCinema too but the CP650 JUST handles film.

We are always on the lookout to acquire used ones to refurb and resell and/or install. We install about 2-3 a year ourselves, in precisely this configuration.
The Datasat AP20 with the analog 35mm optical preamp card is another option, if it's still in production. If it's fully loaded with 16 AES input and output channels it's an option I personally like, because it's extremely flexible as far as channel routing and automation goes. If a replacement audio processor is needed, with film, D-Cinema and alternative content processing capability in a single box, but without the scale of investment needed to go full Q-Sys, it's certainly an option to consider.
Anyone considering the AP20 should keep a spare power supply on site, though - after about two years they are at very high risk of sudden failure.
