This will make no difference; you still have an infinitesimal chance of
a collision.  The data is unpredictable to start with; adding something
to it does not make it any more or less predictable.

Personally I think all your servers are more likely to fall over at the
same time before this would happen.

It's a bit like being worried about a shark attack; unless you make a
habit of swimming in shark-infested waters, you're more likely to be
killed by a falling coconut.
