Nah he won't. I know JJ won't screw up. John Williams approves of him, that should be more than enough. Look what he did with star trek. In fact, he even stated the only reason he did that star trek movie was so he could use that as a reason to work on star wars (or something like that).
The name is irrelevant at this point, remember that even Episode V was amazing though it was directed by Lucas, and there were writers hired for that movie aswell. As long as Lucas is the man behind the curtain, I have high hopes for this new trilogy.
