No but lantern's have altered their own D.N.A. before, becoming another species entirely. I know Kyle has done it.
So the point stands that I see no reason Bruce couldn't do the same with his, especially given that he'd have full experience as a lantern in one scenario!

HOW! When a green lantern ring can already to everything Supes can. Not to mention that with it he could literally be a Kryptonian as well!
Plus this is Bruce we're talking about here. He's a thinker and prep man to the be all end all of it. And he'd have, god knows what all, plans the ring would completely supply him for instantly to implement.
That as aposed to just Superman's abilities when he's already owned Supes numerous times without a GL ring!
Really when you think of it Supes power-set is only a huge Achilles heal in this fight that almost guarantees him a loss. It comes with a huge disadvantage of Kryptonite! Bruce can just surround them with mountains of it while altering his own D.N.A. to Daxamite and going to town on himself.

Unless somebody's seeing something I'm not, the topic-starter didn't specify anything about prep-time. So, GL Batman having time to use .. well .. anything worthwhile against Batman w/Superman's powers is highly improbable (lulz at Batman altering his DNA to mimic Superman's).

This is Bruce Wayne we're talking about here! How much prep time does he really need to come up with, well, anything?
Bruce has contingency plans out the ass for all of this stuff and giving him a lantern ring to help is like the ultimate utility belt. He'd only be limited by his own imagination!
And really how much prep time does, "Mountains of Kryptonite" require to be thought out effectively?
