A friend of mine and I worked up a set of cads for mounting the motor in a small case of it's own with a 2:1 planetary reduction. But He passed away two years ago... 
The reasoning for the pump was that the motor would need cooling and lube for the planetary set. And the car would need the hydraulic power for steering and brake booster. The hydraulic system would keep an accumulator pressurized for use while stopped hence the variable displacement, no need to pump when the accumulator is full..
But yes I still want to do this but four years have passed and I no longer have access to a CNC of any kind. I am done building my new shop and I am buying tools as I can. Ya know anyone with a CNC?
One day soon I will have the power to rule the world!!! @&%#$ Yes we do need an evil mad scientist smiley!

Ok here's some real info (not just my fuzzy memory)
The papers below go into amazing detail and will require many cups of coffee to help with the short-circuiting brain .... They go into testing stuff that no other testing organization gets remotely close to.
The main thing that is important here is that Toyota made a major improvement in motor technology around 2005. Most of their new hybrids use this technology; this is why I say the controller for all of them can be very similar. The paper about the development of this technology is here:

Here's the ORNL paper about the 2010 Prius:

For your project, it actually seems like the system Toyota developed for the Lexus 600h sedans and the Camry would be a good starting point:
SciTech Connect: Evaluation of the 2008 Lexus LS 600H Hybrid Synergy Drive System
There are others, detailing the 2004, 2007, Camry, etc. available from these links.
I know some folks w/ CNC's. It may take some interesting trades, but I may be able to get some time...
I do have solids modeling software, and CNC code generating software (and know how to use it). I do have a Bridgeport mill w/ a DRO and a Clausing lathe. I could get accurate bearing locations with the DRO. It would require some clever design, because machining it from a solid chunk would require a LOT of $$$.
Oh, regarding output splines, etc: The local driveline shop is extremely good and he just got a CNC and broaching equipment. A custom spool or output shaft is no problem here. I'll check his prices today.
