A local place has these on sale; I could easily mount it on the grinder.

This for small bits - 7x10 lathe.

The problem with using that type wheel is the limited surface available
for
doing your grinding, and is likely to yield poor results under normal
circumstances. The typical diamond wheel that's applied for sharpening
carbide lathe tools has the diamond on the side, in a broad area, usually
about 3/4" wide.

Pay attention to the caution already offered on grinding steel. Diamond is
destroyed by steel when applied at high speed----it actually is dissolved
into the steel, cutting its useful life very short by dulling it until it
doesn't cut well. Relieving it on an aluminum oxide wheel at a greater
angle is the typical method of avoiding contact with a diamond wheel.
Using
a green wheel presents the same problems that diamond does---it, too, is
soluble in steel. It's silicon carbide.

So you can't grind HSS on a green wheel?
