Yep. Hope so, anyway, that's what I'm doing, albeit with a hacked climbing switch modified to have flying leads to connect to other switches rather than using the standard switches.
If I didn't already have the hacked climber's switch, I'd probably do the same thing. In fact, I suspect I will as and when I convert the P2 to Di2 (the climber's switch is going on the P5).
