I am in the process of building a druid team. I also have a shaman team, and they are quite similar, but their complexities are completely different. I would go with 2 more druids. Druids are more flexible, as they can tank heal and dps, whereas shaman can just heal and dps. IMO the only downside of 5x moonkin is having to go out of moonkin form to heal. I was going to macro in a sequence of HoTs from the 4 alt boomkin, something like /castsequence [target=focus] regrowth, rejuvenation, moonkin form or something like that, i guess i need to throw in a reset too. Then I'd need some sort of aoe healing macro, same macro, but targeting themselves. My main team has a dedicated priest healer and I just target the tanks target's target, or AoE. I am so used to the holy trinity setup, I am tempted to run bear tree and 3 owls, and use a similar macro strategy. But all this theorycrafting pales in comparison to a video I saw of someones 5 69 druids running an instance, and just murdering everything and using CC to make it ezmode. Only on a few bad pulls did he even need to heal... And even in balance spec, you still have bear form if a boss requires it.
