First question would be: How are you going to avoid the wrath of Paramount's over paid lawyers?
Afterall they aren't above trying to shut down fan sites.
It is a question that has been posed here a couple of times, so while we think of answers perhaps these threads might help you along? Lets have a vote for what and when series 6 should be? How would you improve Star Trek? Seriously If there was a Series 6...
You could also try Fan Fiction for ideas. It is starting to look as if Paramount are taking some of its inspiration from there in some Enterprise episodes
Added the third item, because I missed it
