You could do what I did at EDS, run the checks from cron.  That way you get
to schedule exactly when the checks run, and can spread them out over a 5 to
10 minute period.  You'll want to make sure that either:

1) the last status message is given a long enough lifetime to get through
the night without going purple;

2) after the last status message, send another message to "disable until
OK".  That'll make it go blue until the first morning check.  This would
give you positive confirmation that the checks were suspended and
subsequently resumed.
