I think they will be ok with the change in watering. The plants left on the property survived a foreclosure in 2010 and went a few months without any water (other than rain of course). They seem to be pretty harty now. 
I’ll keep an eye on the watering and make sure I don’t see any issues. This winter I may work on moving the emitters away from the trunks a bit to get better dispersion of the water.
