Well, Adobe needn't jump --
It's already possible, using the \S troff function.  For instance,
here at the Australian Journal of Management, we use \S, \H and the
define function of eqn to automatically get oblique, synthetic Greek
letters in equations.  For instance, to get oblique beta, we define:

define beta	% "\S'+15'\s-1\H'+1'\(*b\H'0'\s+1\S'0'\h'0.2n'" %

Then beta inside .EQ/.EN or eqn delimiters will be printed
with a 15 degree slant, so it's really oblique rather than italic,
but the change in the aspect ratio I suggest above improves the
appearance, I believe.
I can post all our eqn definitions if there's a demand.
