That is, in the ortodox PIE model any item which doesn't fit into regular sound correspondences is put under a different "root". In my view, the ortodox model is inconsistent and divergent sound correspondences like in this case mean divergent word paths.

Actually, Gamkrelidze-Ivanov mentioned a possible protoform *s´ik´wo-, where *s´ is their own "compact sibilant" (a rough counterpart of my own sound law regarding post-velar fricatives), giving *s- > h- in Greek and zero elsewhere, but I find little support for it.

In my opinion, Greek -pp- doesn't come from *-kWkW- (which I find rather absurd) but from *-kWw- resulting from regressive assimilation of *-k´w-. Hence *-kWw- > *-pw- > -pp- by reduction and progressive assimilation (possibly these two changes were synchronic) as in *-k´w- > -kk-.

Besides -k´w-, in my opinion other combinations of velar+w produced weird results in some IE languages, especially Celtic and Latin.
