I've heard that the limiting factors wrt Hubble's current life span are
the batteries or the gyros. The batteries being an obvious one, while the
gyros may not be. If they are just being used for attitude determination
during maneuvers, and not the actual maneuver, it should be possible to
extend it's life so that the batteries or orbital decay are the limiting
factors.

HST doesn't "maneuver" at all. It used to rely on occasional visits
from servicing crews for periodic reboost.
