Even though at one time I liked this idea somewhat, I am now of the opinion that having future movies be remakes of TOS episodes wouldn't really work that well - at least not yet. My main reason being, if the next few movies only cover the first couple of years after XI, then the crew couldn't encounter any of the situations or characters from TOS, because the circumstances that led them to those characters and situations in the original timeline won't happen for several years in the new timeline. Say, for example, they wanted to do an updated version of Arena. In my mind, this would only really be feasible if they set it in the timeframe of the original episode, i.e. 2267, nine years after the events of XI, because the Gorn attack on Cestus III doesn't occur until then. Of course, this is all based on the assumption that the next few films will occur roughly in real time, i.e. XII is released in 2011 so, in the fictional universe's context, will take place around 2260, two years after XI (because XI came out in 2009). So I reckon totally original characters and situations would be better, at least until the films catch up with the TOS timeframe and they match up chronologically.
