The Romans in Europe stopped fighting with large square shields and short swords. By the sixth century they were even starting to lost their taste for bathhouses.
I blame cinema, which provides a quite misleading visual image of how the Roman Empire was for most of its history.
Realistically this civilization cannot look Roman, there is no African red slipware for one thing, and even with skilled craftsmen there will simply not be the knowledge, or probably materials, to build the style of buildings the Romans would have. The would also have a limited amount of texts with them - meaning only a few Roman ideas could ever be preserved, and there would be no papyri, meaning the usual substitutes would have to be found, which would take a while.
The bugs, animals and ideas they did bring would still revolutionise the Americas.
