No problem having drops and mechanical disc brakes, I've got a set of midge bars with Tekro RL 520 brake levers wired to v-brakes (they workwith Mech discs too). I find they work well and offer a nice hand position.
The Rohloff is not so easy.
I've seen a guy use a Cinelli Spinaci to mount the rohloff twist shift, and I'm pretty sure I've seen them mounted on the ends of drops. Neither of which is an elegant enough solution for the bike your putting together (IMHO). The two piece drop bar solution could work better though.
