That Backgroung is really nice imo, one of the best they ever did even on par with Tsubasa BG in my book
Ran's tears and Miyuri's tears + dead eyes at the end of the CG are a nice touch nice as well.
Still not comletely sold on the artstyle, but I like it more than I thought at first glance

It's probably doable if you 'only' want to redo the eyes, but for how much hassle?
