Yes, I absolutely agree with you.  Thanks for pointing that out.  I was 
a bit worried about the fewer I/O pins.

Primarily because I have several 3013's in a drawer, and no 40-pin dip 
dsPIC's.  But even if I did, it is not clear that the job would be any 
easier, because the pins wouldn't match the way the existing socket is 
connected.  It seems like it might even be harder.  There used to be an 
old trick that us hobbyists used, that you professionals would turn up 
your noses at.  :-)  It is called "dead bug soldering," and involves 
turning an IC on it's back, so that the legs stick up in the air (thus 
the name).  Makes it a lot easier to solder small wires.  Anyway, doing 
that with a 28-pin socket in the middle of a 40-pin socket would be 
easier than trying to use a 40-pin socket wired to a 40-pin socket (to 
change the pins).  Or at least it seems that way to me.
