All the more reason to scrap them entirely (thus why I should never go into politics).
The copyrights and trademarks for CT, RD, and CC are all owned by Square, unless I am mistaken. Thus the only political concerns they'd need to take is to not horribly offend Masato, Mitsuda, etc. (Square would, after all, still like them to make games in the future).
As long as the new team is properly dedicated, I am fairly confident that such a team could create a compelling addition to the series (much in the same way that Batman Begins, Transformers Beast Wars, Enterprise, and other such instances were able to stay true to the underlying themes of their respective series despite being developed by other individuals).
EDIT: I guess my point is essentially; for every Herodotus, there is a Thucydides. For every Thomas Hobbes, there is a John Locke. Every Thomas Jefferson, an Andrew Jackson. And so on, and so forth. Great things need not end with those who started them.
