So this is what I've found for diphthongs in *o (I'm ignoring all long
diphthongs whether in *e or *o because they'd have a laryngeal
explanation, and I'm ignoring those in *a). They're extremely rare. I
didn't see any distributional patterns. Most consonants are not
followed by any o-diphthong. Counterexamples are few and far between.
Presumably those few that do exist come from *H3ei and *H3eu preceeded
by a consonant. That's not certain though. If *H3 voices preceeding
consonants than there are some that can't be explain with a laryngeal.
On the flip side o-grades of e-diphthongs would be common.
