The 28-pin version does include a test pattern generator, currently just two patterns on the absence of 625 input. Deleting that selection function and having only a single pattern would free up one pin.
Doing away with a 'No Signal' LED drive would free up another.
Turning the Vpp/#MCLR into a standard input and moving a few others around would free up a third pin.
Deleting one of the Gamma settings so it's either linear (1.0) or Gamma decode (2.0...or any other value) would free up a forth.
So, in all it could be done.
As reluctant as I am to move in time to a 40-pin device I feel it's the way to go. For those a little wary of wiring up anything with more than 16-pins, it's really just the same exercise, just on a larger scale. concentrate and eliminate distractions...turn the damn phone off!!

It's a shame, perhaps a blessing, that no-one produced a package mid-way between 28 and 40 pins. Say 34...though 32-pin packages are common in parallel RAM devices.
