A Campaign Idea that needs tidying up

[Hopeless]

Got this idea for a game which is set around the reopening of an old gate that allows travel across a great rift.
About twenty years ago it was sealed after a bitter war forced it to be closed as the other side was being conquered by an as yet undisclosed enemy.
The opening game is a murder mystery because one of the head administrators has been shot dead with no indication as to who was responsible.
Investigation will eventually discover a massive corruption ring that was selling would be colonists sleeping in suspension pods into slavery and far worse with the murder victim apparently one of the people involved.

The idea is that the game will lead to the eventual reopening of the Gate but prior to being opened a small team is sent through an even older smaller gate to investigate the other side revealing the enemy have been alerted and are waiting to ambush the new arrivals forcing a fighting withdrawal with the PCs being stuck on the wrong side of the Gate which will lead to the start of the Second Campaign.

Any tips or views on this?

Anything that might need to be explained or needs to be available for the players when designing their characters or some kind of handout to explain the setting?

Any ideas I've missed?

I was wondering if this could be done via T2300 but I figure regular Traveller rules will suffice.

It sounds like a fantastic set up for a campaign, a bit more inspiring than 'a thousand world empire or great age'.

Fading Suns works on a lot these ideas. Fading Suns also played on the idea that various things happened on the other side of closed gates, so when they reopened there are...surprises.
