I would do one, mayb two more SG-1 movies (mayb a big epic two parter or two which are connected in some way) which is O'Neill heavy where hes back in charge of the team.
- At the end of this I would have the SG-1 team disband and mayb even re arrange the SGC
- Carter would either leave for a civilian job connected to the Gate or be posted elsewhere
- O'Neill would finally get to retire
- Carter and O'Neill talk about going on a date (but leave it open ended)
- Daniel gets a job with the Atlantis expedidtion
- Teal'c leads the Jaffa
- Mitchell finally feeling he doesnt need "the band" to get by puts together his own team and continues exploring the galaxy.
- Somewhere in these movies include Ferretti
