That's true Paul but even the quick & dirty drawing you did shows a lot.
For instance, the most obvious thing in the way when looking at my -4 is

the

oil pan.  I notice in your drawing that there is a very "customized" pan.
Not impossible but not easy either.

Naw it is easy. You just cut it with a high speed disk grinder and braze
on a flat piece of sheet steel.>>>

Take a look at what the Tracy style engine mount looks like.  The two holes
that open to the oil pan could just as easily be left solid, and one opening
under the sump cut to match a piece of round tubing.  (Or whatever shape you
want the lower volume to look like)

It looks like the oil pickup could easily be plumbed to whatever location
you want to use for an oil volume.

I always worry about a long pick up tube for an oil pump. When the oil
pump gets a bit warn it don't suck so well. Especially after sitting for 
a week or two.  Chevy used to put the pump in the bottom of the pan 
for that and other reasons. The old Chev V8 was known for its  excellent 
oiling system under lateral G loads.  Lately the LS1 engines have 
an auto transmission style pump concentric with the crank. I wonder 
how that is working out long term.
