2008 - 2010 engine in 1990 GPX

This has obviously been discussed before but can’t find it? Is is practical to fit a motor from a 2008 and later carb GPX250 engine into a 1990 GPX250 bike? If anyone has done it what is required to make it happen.
Thanks

Swap engine over
Swap exhausts
Swap carbs
Swap harness
Swap ECU

Done! You can do with less, but performance and driveability will not be optimal.
