You've got it in the right ball park, Rusty.  I also eliminate the stock cowl air intake and put my oil scoop there.   See my oil scoop, it is 10.5" wide and averages 2 .5" high for around 26 square inches.  An Aussie, Ian ,appears to get away with a bit smaller inlet (his the white bird).  I suggest making the bottom lip with a bit of a smooth airfoil like entrance to ensure that when you have the nose up in a climb that air will still be induced to flow around the lip and into your scoop. 
 
Thanks for the comments, and pics Ed.  I spent some time at the hanger this afternoon, and have decided that the evap core is somewhere in the top 10 wonders of the world. 
 
My Setrab just takes up too much space (long, and wide, but thin) to be able to fit very.  Since the bottom of the cowl is curved, the larger foot print of the Setrab lifts it up higher than the thicker evap core.  I found that I can slide the 3rd evap core just under the starter, and be able to sneak the exhaust pipes out behind it.  The fittings will even end up being on the right side, which is perfect.  Mounting it will be a breeze, and even the scoop won't be that bad to make.  This is just going too well, so I must be doing something wrong :-)
 
Now, for another question.  Is there such a thing as a compact oil filter, that has a remote filter mount available?  My old remote filter mount, and filter is HUGE, and heavy.  What are my compact oil filter options?  
 
Now, a question primarily for Leon, and Todd- Now that I'm back to my plan of using the stock pump, and one EWP, I'm trying to sort out the mounting options.  What just occurred to me today, is that I can cut off most of the inlet pipe on the stock water pump housing, and weld on a flange that will bolt right to the outlet of the DC EWP.   I realize this is a plastic flange, but I don't think it will have any trouble holding the weight of the pump.  I will have to be careful to clamp the inlet hose to the EWP to an engine part, so it doesn't put any extra strain on the pump.  Assuming all that, do you see anything wrong with this mounting plan?  If it looks too flimsy, I can always add a brace from one of the water pump bolts, to one of the otherwise useless mounting tabs on the EWP.
 
Thanks,
Rusty (wishing some parts had arrived, so I'd have something other than cowl to work on)
