Not close at all, sorry. the paf pro is that bit hotter that makes all the difference to me, the paf is ok, but not particularly spectacular. For instance, i had a paf7 in a 2127, was, well, not particularly inspiring, and have a paf pro in my s540 which rocks like a bastard. pretty much similar construction 9mahogony with bolt on maple neck) so i can pretty much say they're just not the same.
Same as the paf pro rokkin like dokken in basswood rg's and the old jems, but the paf7 just doesn't bring the same level of awesomeness at all, in fact, a bit dissapointing.
So, I'd say beware.
Actually, it's comparable to the difference between the fred and mo joe. I am not a massive fan of the fred (it's ok, but not awesome) but love the mojoe as it's just hotter and has that awesome thickness to notes when soloing and that smoothness comparable to the paf pro.
But, your mileage may vary, paf7's tend to not sell well (difficult to get rid of) so it'd be a cheap experiment anyway
