I'm using a 2-10 to control both Nav lights (middle position) and Nav +
Strobes (up position) like figure 11-18 in Bob's book. I also want to
turn on the cockpit/map lights when the Nav lights are on. Is there
anyway (using relays or something) to do both?

Nav circuit is 10 amp, while the Cabin/Map light circuit is 5 amp.

May I suggest that you leave these lights run all the time?
Just dim them to minimum when not in use? Lamps will last
just about forever at a voltage just above that required
for just-visible light output.
This simplifies your system and avoids having a blown nav-light
fuse put your cockpit in the dark also. Further, some minimal
panel lighting should run from the e-bus . . . or perhaps from
their own batteries. I've seen some nifty LED panel floods that
run from internally L-Ion batteries good for hundreds of hours
of run time.
