The head of NASA was asked about that at this afternoon's press conference.
Basically, he said it would be difficult and the HST might die before they
could
arrange it anyway.

What about using electrical powered engines ? After all time in on our
side in case...

You still have to design the new mover, docking gear, etc etc etc.

It's probably going to cost as much as a shuttle mission. All of which
doesn't address scheduling issues (how sure are we that it could be done
in time).

And just after Opportunity landed, Weiler, Theisinger and Elachi give
O'Keefe a sign:

agreed...

but I was under the impression that those issues should be also solved
for the "desorbit booster"... assuming one will be indeed built (I
personally doubt it).

I don't know how confident NASA is with it's ionic propulsion (seems
that the latest test probes were quite successful) but I don't see any
reason not to consider it... and actually decide which way to apply
the delta V at a later stage !
