The mics above the drums are going to get more cymbals/drums than you probably want. I think you'll still need your mics placed carefully to capture the whole band.
Thats what I suspected.
So I think overall, I have I three options
Run one machine when board is in audience
SBD and Mics into same machine
Run two machines when board is on side of stage but lighting tech is in audience
SBD into one machine and Mics into a second machine. Sync during post
Run one or two machines when both are on side of stage
This is where I need to be prepared for several configurations
Getting there earlier to assess the situation ( not assuming a plug-n-play situation every time )
Getting longer cables in cases where I need to have the mics at stage lip to capture the room
Since the internal mics on the DR-2D came out pretty decent, and the DR-40 supposedly has better quality internals, this may be a good opportunity here.
It wouldn't hurt to run both machines in DualMode and pick the best sounding Mic recording of the night
The lesson in all of this for me is not to assume outdoors is like taping in a club + the 'bleed' (for lack of a better term) you get from being outdoors.
I need to be better prepared for any and all circumstances.
I'm gonna need a duffel bag soon
