Multiple times.

The most optimistic estimates are on the order of 4 years.

The most optimistic estimates of the return rate are on the order of 6-8 /8s (not the
100% of 22 /8s you are postulating).

The legal expenses would be extreme.

So, for $ALOT and 4 years of effort, you might get back as much as 4 months of
address space.
