Another option is to setup a MS pair One Omni for the M and one figure eight for the sides.
EV 635a and two EV CO4. wired in series and out of polarity pin 2 to the mixer. pin 3 to pin 3 on second mic pin 2 on second mic to pin 3 on mixer.
you will have the figure 8 pattern on the two CO4 mics and the EV 635a
Middle side can be translated from mono to all the other stereo patterns. Co 4 mics are 65 for the pair at GC.
You could also place in a large garage and leave the doors open Keeps them a little dryer depending on the wind direction.
Yes wind guards would help to clean up the sound.
