Even if Gurren Fagann was redone by Jim Davis, it'd STILL be Gurren Fagann. Only with a lasagne-addicted cat & a drooling dog.
No, the ONLY way I'd watch it, was if it was redone written by someone else other than Gaynax's shitty writers & with character designs by Hisashi Hirai.
Oh, but it's already been done. It's called Heroic Age. Ah well, I guess I won't have to watch Gurren Fagann then. That'll save a lot of time then.
