We certainly don't find *pk^u- within the
declensional paradigm of *pek^u- (and we wouldn't
because *e is always paradigmatically strengthened
in nouns to avoid assyllabicity of the root).
The stem *pk^u- may exist as part of another stem,
but not as part of the declension of *pek^u-.
Since I was refering to paradigmatic strengthening
of *e in _nouns_, all other "counterexamples" you've
mentioned are irrelevant because they are verbal.
The ablaut of athematic verbs (such as *?es-/*?s- and
*?ei-/*?i-) is completely expected due to the shift
in accent placement. The zero-grading of verbs
with an accented *e- augment is also normal and
expected.
