Bah. You might find the following approaches to the above a little more 
sophisticated and interesting:

Title: Experiments in Multiresolution Modeling (MRM). 
http://www.rand.org/publications/MR/MR1004/

Author(s): Paul K. Davis, J.H. Bigelow 

Abstract: This study describes the motivation for multiresolution modeling
(MRM) within a single model or a family of models. After introducing a new
measure of consistency for models of different resolution, the study discusses
in some depth obstacles to and methods for multiresolution modeling (also
called variable-resolution modeling), illustrating issues with a detailed
military example involving precision fires. The study highlights the value of
visual design, array formalism, formal mathematics to identify natural
aggregation fragments, integrated hierarchical variable resolution (IHVR)
yielding "trees" of variables, estimation theory, alternative aggregate
representations called out in a user interface, "stretcher variables," and
computational methods to identify natural phase transitions and facilitate
calibrations.

Not exactly what you were getting at, but this approach certainly doesn't
suffer from the "mathematicians writing on the board for it's own sake" 
problem you alluded to. Bridging the speculative and the practical couldn't be
more central here (as everywhere.) Reminds me of something John Von Neumann
once said:

"The sciences do not try to explain, they hardly even try to interpret, they
mainly make models. By a model is meant a mathematical construct which, with
the addition of certain verbal interpretations, describes observed phenomena.
The justification of such a mathematical construct is solely and precisely that
it is expected to work."  


This might sound a little off-the-wall, but have you considered sitting in on
some graduate classes in the sorts of areas you're interested in at Berkeley,
just for the sake of generating more discussion with people in the field? 
Ill bet bouncing everything in your post off people there would generate a lot
a lot of return for a small investment of your time. None of my business but
it's at least worth a thought.
