The major advantage for a relaunch, is that you already have everything done... the cast is assembled (and I'm assume they'd be chomping at the bit to come back), the production crew has a proven track record, and it would take a matter of weeks to get sets rebuilt. Plus, with CGI being as cheap as it is these days, it would be a pretty quick and cost effective run.
As long as they brought back everyone, including Anthony Montgomery.
