There is one possibility which is not ideal but works quite
well for most cases. This is to use the "fat" primitive in eqn,
which prints what it applied to in "heavier" format, by
overprinting two copies horizontally offset. The amount of the
offset is controlled by the value of the parameter "fat_offset".

Have a look at the result of:

.EQ I
size 30 sigma~~
size 30 fat sigma ~~
.EN
.sp
.EQ I
size 30 sigma~~
set fat_offset 0.5
size 30 fat sigma ~~
.EN

and try varying the value of fat_offset -- e.g. 0.5, 1.0,
2.0, 5.0, 8.0 ...
(and see the nasty that happens at 9.0+).

Not all characters give nice-looking results from this method,
and in any case it is not a true emboldening -- the horizontal
(or nearly horizontal) elements of a glyph will not be thickened
at all.

Still, it may help!
Ted.
