This might be true of some pre-stage of the protolanguage, but not of
PIE. There are many roots ending in *-CC. In some cases it can be
demonstrated that the final consonant is an old, obscured suffix, and we
can even recover some features of pre-PIE phonotactics, like a
preference for "balanced" *CCeCC- structures rather than *CeCCC-. Thus,
the addition of an s-extension to a CeCC root changes the position of
the root vowel:
*h2aug^- 'grow' but *h2weg^s-
*h2alk- 'defend' but *h2leks-
*meik^- 'mix' but *mjek^s-
