No. I'm saying that the change from kw to p must date from after Celtic was introduced into Ireland, because that particular change never happened in Ireland. Since that's usually dated to between 700 and 500BC, and proto-Celtic ceasing to be spoken as a single language between ~1200 and 800BC.

The point is the very large gap in time between the centum/satem split, with the latter merging the k'w and kw sounds, and the full labialisation in Celtic, Greek and Italic. It would be very strange for Lusitanian to be undergoing labialisation (an early 1st millenium BC phenomenon for everyone else) before it had differentiated kw and k'w which is something reckoned to have happened before - probably well before - 2000BC. It therefore looks as if Iccona could not derive from PIE *ek'wo- and isn't Epona.
