Nos:
To be candid, no, I've not been in contact with such an individual in this day and age of biblical proliferation.
I did speak to a missionary who recently returned from Cambodia, who spoke of such things, though.
Apparently a group of people "came to faith" merely by observing the creation. When they were introduced to Christians they (allegedly) instantly recognised this as what they had been worshipping.
I can't (in all fairness) offer that as proof positive, however, as I didn't get the full story. Besides, it would be second hand at best.
Regarding scripture being scripture, bear in mind that a good quantity of it was letters and compiled histories.
If anyone were to later dig up our discussions, they may (or may not ) later canonise them.
Personally I've had some incredible experiences. I generally use the framework of "Christianity" to explain them, but I'm just as much at home explaining them in other frameworks, depending on whom I'm talking to.
Have you ever read "The Heavenly Man"?
(I'm about to leave for a couple of days, on a road trip for work. Sorry if I suddenly go quiet)
