Why don't you save the host keys then?  Change your reinstall process
to install the saved host key rather then generate a new one.

But anyway, StrictHostKeyChecking does affect changed host keys.  You can
easily set it to 'no' for only certain hosts.  Even with 'no', certain
types of authentication will not be allowed, that's an easy behaviour
to change (1 or 2 line patch), but I would recommend you install known
host keys instead.
