Technically it will be possible, however this won't come cheap. You can expect it to cost at least £1k for the new head unit alone, plus the cost of the new digital instrument binnacle, plus labour.
By the time you've done all that you won't be far off the price of changing the car for one with them already fitted. A newer car would also have the swoopy rear lights that you crave.
I might be wrong, but i'm not sure if you can do job 1 without doing job 2.
