Reasonable suggestion, in many ways.
However, I've spent some time looking into what a QPL is (we don't build
military equipment, so I was unfamiliar with the term).
Unfortunately, after reviewing what is involved in achieving QPL status,
I think if we went only with QPL components, a 10K 0402 chip resistor
would no longer cost only $0.002.  
I think I need to determine an acceptable compromise between QPL
approval process and my own gut feeling on whether a part is a good
cross.  I have to figure out how to document my gut feeling so my
evaluation process is repeatable for others.

Maybe I should have chosen different terminology.  I think I'm opening
this up for a Dewey free-for-all...  :)

Hi
Why not consider adopting the Military QPL's.  Presumably your work
would be largely done.
Monitoring would be your continued responsibility.
