IF they still had a Shuttle, they could probably fix it.

Typical HST service missions cost more than the HST itself. It's
cheaper to replace the HST than to fix it, at least with shuttle
technology.

Replace it with what, the Webb?

Building another one like it from scratch would be cheaper than a Shuttle
mission. And you don't even have to grind a mirror: the one that Eastman Kodak
made, without the wrong-way aberration correction, is sitting in the
Smithsonian.

A new one today would be around $2B, a Shuttle mission around $1.4B to fix it. In any case, if the Hubble goes down completely, there will be a considerable gap between its end-of-life and the Webb, if it finally launches. Also, the Webb is optimized for IR so images won't be the same as Hubble produced.
Maybe with false-colour?
