aftertouch

[Ron & Lorene Shiflet]

I'm working on a Baldwin console.  The plate has 40 stamped on it.  It's a pretty good piano and is about to go back to its home.  The action is a little on the small side .The regulation is pretty good but I am needing more aftertouch.  

Key height is 2 1/2" above the keybed.
Hammer Blow distance is 1 3/4" to strings.
Letoff is about 1/8" in the treble and 1/4" in the bass.
The bass and midrange white keys are pretty good with correct aftertouch.  Some of the whites in the higher treble have shallow aftertouch.  
Sharps have little aftertouch and are terrible.  They sit 13mm above the whites.
There is nothing obviously wrong such as too many punchings under the keys. This piano does not appear to have been tinkered on by an unqualified toooooner.  

My choices are:
  1.. Raise keys.  
  2.. Decrease hammer blow distance.  
  3.. Increase letoff.
  4.. Increase dip.
With choice 1, I'm hesitant to do this as the keys are right up against the rail.  With choices 2 & 3, I feel like I'm losing power.  With choice 4, I feel like I'm chasing symptoms and not the real problem.  

It may be that the action is compact enough that I just need to squeeze what little I can from all 4 choices.

Any thoughts from the list?  Am I overlooking something?  Thanks in advance and happy holidays to all of you.
