Yes, it's possible to ride in the drops with the saddle tilted up.

I ride with saddles either dead level or slightly nose up. Tipping the nose down will put too much weight on your hands/wrists.
To me, the perceived need to lower the nose signals an incorrect saddle or improper overall fit on the bike.
*EDIT* Incorrectly said "raise" instead of "lower" the nose.
