@rockygems123 - I'm definitely looking forward to the "snacking cookies"! 
As for my research project, I won't have time for baking until this weekend, but I did a preliminary check of the chocolate cookies. As you can see in the photos, although the package weights are all 9 oz, the Dewey's cookies are smaller than the Nabisco ones. The flavor comparison was interesting—the Dewey's Brownie Crisps are only a teeeny bit sweeter than the Nabisco wafers and will be absolutely fine as a substitute in crusts and related applications; the Hot Cocoa Cookies were much sweeter, so I think they'd also work, but less or no sugar would need to be added. (They are yummy, though, so I'm sure they'd be great if you just want a treat!)

And interestingly, when comparing ingredients and nutritional details, Dewey's Brownie Crisps have a slightly cleaner ingredient list than the Nabisco wafers even though the fat content is a bit higher, so if I'd been comparing without being forced to do so, I might have even gone for Dewey's in my baking before this point.

Anyway, I'll come back and update the thread with results after the baking test...
