Italo-Celtic : p-kw > kw-kw

One of the main traits of Italo-Celtic is the assimilation p-kw > kw-kw, and the principal examples are:
 
IE *perkwu- "oak, mountain oak" > Lat quercus
IE *penkwe "5" > Lat quinque
IE *pekwo: "I cook" > Lat coquo
 
Are there another examples?
May this assimilation occur in compounds, like, for instance, *pro-kwolo- > *kwro-kwolo ?
Similarly, may this assimilation  occur in bh-gwh, p-gw, p-ghw,  b-gw, etc ?
