Grisha was well know and would probably have been defeated before he learned how to use the cordinate plus would the past Reiss eever helped the man who sterminated their family?

Eren was a wild card, the hometown didn't know how he looked like, he was determinated to defeat titans at all costs so it was unthinkable for him to ever swich sides.

There is also another factor to consider, in order to trasform in a titan they must have a set will it's possible that Grisha wouldn't have it to fight aganist Zeke.
