Whoever picks up your team knows they are getting a somewhat unknown sched. I wouldn't worry about it.
I'm assuming you're talking about games proposed to you.
If you are going to be gone the next year, I'd send a site mail and to the coach who requests a game and let them know.
If you'll be gone (assuming you move up), you've obviously had some measure of success, so I'd schedule the way you have in the past.
