flight recorder, GPS-enabled ELT, mainly-passive alert
and transmit-on-alert-only transponder ?

Speaking as a Libelle driver with one spare panel slot and a maximum
battery capacity of 2 x 7Ah, I'd settle for something like a combination
of the Zaon MRX and a Microair or Filser transponder in a single 57mm
package. I'd be happy to use one battery for transponder + radio and
reserve the other for varios, GPS and iPAQ.

Both these transponders fit a 57mm mount and are fairly light with low
power consumption. Adding the TPAS capability and using the same display
should make little difference to the package size while adding about 15%
to overall power consumption.
