   Can I change the inter-letter spacing in troff/groff, whilst retaining
   proportional spacing?

From gtroff(1):

       .tkf f s1 n1 s2 n2
              Enable track kerning for font f.  When the  current
              font  is  f  the  width  of every character will be
              increased by an amount between n1 and n2; when  the
              current  point size is less than or equal to s1 the
              width will be increased by n1; when it  is  greater
              than  or equal to s2 the width will be increased by
              n2; when the point size is greater than or equal to
              s1  and  less  than  or equal to s2 the increase in
              width is a linear function of the point size.

If this doesn't do what you want, perhaps you can explain more fully
what changes you wish to make to the inter-letter spacing.
