But *does* Pasquariello's modification overcome the serious drawbacks
of Fama-MacBeth?  I have not seen any evidence that it does.  (If you
have citations which show this, I'd be interested in seeing them.)

Instead, why don't you use alternative methods which are *known*
to work?  If you have panel data (as is usually what people have when
they resort to FM), then why not use appropriate statistical tools
like PROC TSCSREG and PROC PANEL instead?
