If headworn, consider rotating the rig so it faces directly toward the close PA while you are able to face center stage.
^That assumes making a typical Left/Right stereo stack tape, the way most tapers would go about doing it. Which is the safe bet.
I hesitate to mention this, but will anyway in case you want to get somewhat oddball with it. I also mention this for the others contributing to the tread who may want to try it sometime.
Accidentally, via occasional instances of two of the four channels of my stealth recording setup not working properly, I've discovered I sometimes prefer making a Center/Rear channel recording over a traditional Left/Right one, particularly in a stack-taping situation. That would be done by having one mic facing directly toward the near PA speaker and the other mic facing in the opposite direction, out into the room. At this venue something like that would be achieved by wearing your head mounted rig the normal way without rotating it, as your right ear will be facing more or less directly toward the PA.
You'd then end up with one "drier" stack channel, and one somewhat "wetter" room/audience/ambience channel, although that "wet" channel will also tend to be dominated by content from the close PA whenever the band is playing. Consider the resulting raw recording to have a Sum/Difference (Mid/Side) relationship rather than Left/Right. You can run that through a typical Mid/Side to L/R decode step to get a standard L/R stereo output. The dry PA stack channel serves as the Sum or Mid channel, so that content fills the center of the resulting stereo image. The ambient channel serves as the Side or Difference channel and gets spread out to either side, and you gain the ability to vary the level of it to achieve the best stereo feel and depth. Funky but it can work quite well, providing some welcome control over direct/reverberant balance, more stereo interest than a straight L/R stack tape typically does, and makes for a wide yet symmetrical portrayal of the room ambience and audience reaction in the resulting recording even though you are way over to one side in the room.
If anyone tries this, feel free to hit me up to discuss a few mixing details.
