I've heard some great, not good great, lawn tapes with the 4060 series mics. All depends on the delay arrangement, but it is possible on a stand to pull a nice sounding tape with them from the lawn. Wouldn't reccommend a wide spread (no more than 24" due to phasing. If you do post work don't run roll off at the venue, if you don't do post, I'd run a little high-pass.
