Die Hard Year One with CGI 'Moonlighting' Bruce Willis?
20th Century Fox could do Die Hard Year 1 with CG/deepfake Moonlighting era Bruce, don't let the franchise go out on this awful last film!

Maybe your suggestion comes from a very nice place in your heart as a fan, but I would say it's better to just let it go.
Just watch the first 3 movies and ignore those DHINO entries.
As of 2023 those deepfake/deaging/CG-whatever things still don't look 100% convincing (I can't believe people praising the deaged Harrison Ford sequence in the most recent Indiana Jones film). Bruce is gone, his acting choices/charm/voice are not there anymore, anything else would be an impression/parody of him.
Let it go. =(
Trust me, given enough time they will "honour" him for the sake of profit.
It will happen, as long as there is money to be made.
