Shaman duo partner questions...

[Fishbait]

So, i'm currently a 54 shaman and my buddy I duo with is currently a 53 monk.

The end game plan is to get to 57+ then start hitting higher value cash camps duo to start making money to buy Epic MQ's/etc.

But...the monk for him is getting quite stale, the upside is that he also already has a 55 Necro which I recently found to be an amazing duo partner for xp with that is nearly as good or equal to then a monk.

I guess my question basically boils down to, will a Shm/Nec duo be able to do all the cash camps(or most of them) that a Shm/Mnk could do?

*Note: I know he should play what he likes more...but with his monk at 53, he'd tough it out to 57+ just as a cash camp toon then switch to necro. But if the necro can do the camps with the shaman anyways, then he'd just switch now.

Edit: Also any information on duo'ing in Velious for easier dragons and the like would be great too!
