With the help of Darktrain and Naiant, I've put together an ultra low profile Schoeps CCM setup that is reminiscent of the CMR/Tinybox (or battery box) setup that Darktrain and others (jerryfreak?) pioneered and popularized in the past year.
I was intrigued by the CMR setup and asked Jon of Naiant if the Tinybox could power the CCM mics (reterminated to TA5) since it can provide 12V of phantom power. His answer was yes (and I asked Schoeps customer service as well and they said that theoretically there was no reason it would not work) and Darktrain was kind enough to reterminate the Lg cables (possibly the first time it's been done).
The main difference between this setup and the CMR/Tinybox setup is primarily that this setup utilizes CCM mics instead of the MK+CMR, and because it uses CCM mics the powering is different, utilizing 12V phantom that the Tinybox can provide (but not 48V).
So, the setup is:
Schoeps CCM > Schoeps Lg cables (could be the Ug variety as well) reterminated from XLR (x2) to a single TA5 female (5-pin mini-XLR) > Tinybox v1.0 (with TA5 male jack) > Recorder (you can throw in a TA5 extension cable in the middle to use it with a stand, or without it when doing stealth work)
Huge thanks to Darktrain for reterminating the Lg cables and providing the TA5 extension cable (utilizing all 5 pins due to requirements of phantom powering) and to Jon (Naiant) for making the P12 version of the Tinybox. Without them and their skill/craftsmanship/devices, none of this would have been possible. The Tinybox v1.0 is especially nice because it has the inputs/outputs on the same top panel and so this setup can easily be used for stealthing purposes (slip it into a pocket).
The main drawback of this setup is that it lacks the ability to switch capsules that the CMR has, but if you own or prefer to use CCMs, then this is a nice setup. And you can use just one set of Lg and extension cables and can 'switch' between different sets of CCM mics.
I haven't tested it out in real life yet, or done any batter life testing, but Jon estimates that the lithium battery may last some 10 hours with P12 to the CCMs, which would be incredible, and comparable to the Sound Devices 702 with a Sony 6600mAh battery that I was using previously.
