My changelog wouldn't be as extensive, but I will make sure that it covers some of the most important aspects that can't be absent.
First of all: I would try to get all the original voice actors back.
Also, it would be a huge priority for me to get a better animation studio for the series (the original was fine, but I'm aiming higher for this reboot... TMS would do).
The third item on the list would be to give direct orders for the animators to stay away from the new standards and keep using the same coloring/shadowing bases. This is a series that just wouldn't work in the new "bright/reflective" style that is so common nowadays.
Fourth: If you have to cram songs into it, that's fine, but try to make something memorable with it, it would help immensely to raise the global appealing of the movie/show. In other words, get the people who made the songs from Animaniacs! (no, I'm being serious... don't you remember ALL that soundtrack?
).
And finally... don’t make stupid changes to the series; don’t re-design the characters to adjust them to the new standards of appealing (they're dinosaurs xDD!) nor don't you dare changing the names.
With all that, I would be happy.
