Best way to get list of public addresses in keypool.

[TangibleCryptography]

For a site I am building I don't wan't to use a hot wallet. 

I would like to extract all the addresses from the keypool (1000) and load them into a database.
I considered using pywallet but that appears to only extract "used" keys not keys from the keypool.

Any ideas?

I know there are methods to build a set of public/private keypairs but that requires me to import 1000+ private keys back into a wallet.  Seems taking a new wallet, increase keypool to x and then dump all the public addresses from the keypool would be the easiest and most secure method for a cold wallet.
