Absolutely. But like anything
that dangerous, one must use caution so there isn't too much low end cancellation in the other instruments.
When I first started applying the 3rd mic (D6) I was fucking tickled. But it did tend to eat up and dominate a lot of lows when the chunking began. It's easy to get carried away, (which I do on occasion).
You'll find out how much you'll need once you add the drums and bass. I try and hold back a bit on excessive high end sparkle and low end massiveness so there's something to work with in the mastering process.
I do my final mixes to -5db so what ever needs to be done in mastering has some space to work with...
