In reality, the last of the Dassault Mirage, Mirage 4000 was a 1979 private venture cancel in the early 1980s due to lack of domestic interest (as the French Air Force wishes to focus on the Mirage 2000), and Export potential (competition with the more mature American F-15 Eagle, Saudi Arab choosing other fighters, and fall of the Shah of Iran).
But what if, Bored Omnipotent Being wants to play a game with you?
What if, you were send back to 1st of March, 1979 (about a week before the first flight of the Mirage 4000 prototype) to revive the Dassault Mirage 4000, and make it remain relevant via upgrades, retrofits and further development variants up to late 2010's-era (or even better, late 2020's), what would you have done? and how would you have done that?
In aid of your task, B.O.B. provides you with 70 metric-tons of Gold and 70 metric tons of Silver bullion (rough calc estimate 1.15 billion USD at 1979 value), but no uptime technical information will be provided.
Edit: Curious as to what @Rufus Shinra would have done?
