Dissimilation of gW/kWVw to gVw/kVw

While working on another problem, I accidentally noticed that, in Pokorny, there are NO roots that have the form labialized dorsal stop +V + w-.
 
For reasons I will not trouble the list with at this time, I believe it is possible that earlier roots of the form **gWew- and **kWew- were dissimilated to **gew- and *kew-.
 
It seems odd to me (if true) that no one has noticed this before; I have never read of it.
 
Does anyone know of a reconstructed IE root that has either the form *gWew- or *kWew-?
 
Of course, one can assume that they simply never existed; but would that not be strange?
 
As far as I know, every other consonantal phoneme of IE except *w has an attested C + V + w- form.
 
Your help would be greatly appreciated.
