Just a thought - if you suggest **/ka, ke, ko/ > */ke, k^e, kWe/, why did
this not also happen with **/ta, te, to/ and **/pa, pe, po/ etc, which can
equally well be palatalised or labialised. If a collapse could be tolerated
after a non-velar consonant, why did it have to be preserved after a velar?
