Very interesting!  
Making your own top-mount GPS for the D7 just like the new

If I understand what you are suggesting...

Using a tiny GPS like the one from Byonics, taping off the D7 +V
from the existing D7 external power connector center pin, and
GND via the GPS shield connector (and having a 5v regulator
somehwere in line..)
