I will be impressed if you hit 25 balls per cubic inch on a forward bias spool. Optimizing your flow path is going to be essential.
Ok, so I think I'm going to move forward with a simple marker design as shown in the OSM thread, but on a slight tangent.
I've come up with so far (some mentioned in 1st post of the other thread):
Mech/ Pneumatic Sear
Off the Rack parts where possible (existing barrels, regs, feednecks, frames, etc)
Standard autococker frame spacing
Air cut off technology (DYE type)
Female Regulator threads
LED board (cheap) [possibly Scenario Dreams board]
Standard 10-32 ASA mount holes
45 frame
Anti-chop eyes
Minimal milling
A/C threaded
Ego style feedneck
18-25 shots per CI of tank
Forward bias spool
Single tube body
As low of OP as possible (not sure what this'll be, depends on spool design)
So yeah, if anyone else has ideas on what they'd like to see let me know; I'll try to figure out what can be incorporated and what may be too hard to do.

That's just a general idea. I know my etha is right around 19, so if it gets more than that I'd be really happy.

I'm trying to figure out a good design for the drive train, but even narrowing it down to a forward bias spool, there's a lot of options. I may jus stick with designing as much of the body as possible then coming back to the drivetrain.
Now I know why it takes so long to put out a marker.

Don't worry about the utmost level of refinement, that can evolve and come with time. Just play around with the general arrangement making sure you pay attention to what actually makes it tick.

For thinking, take a look at Andy's site, zdspb.com for marker design and hints. Also look at the http://paintball.newkamikaze.com site for how quite a few guns run.
