Why can't you use "ULX unstuck"? It's intended for admins, but, I suppose you could give players ulx unstuck ^ capability.
Someone also wanted modified unstuck.
I searched our forum for "stuck" and found this -
http://forums.ulyssesmod.net/index.php/topic,7259.0.htmlIt's a start to what you're asking for.
Perhaps asking in that thread might have been a better start? Like "did anyone finish this, or can anyone finish it for me? I'm seeking the cooldown and spawn ideas just like the original poster did"
Perhaps seeing if the original poster still visits here, and if so, leaving him a private message, to ask if they ever completed it.
Even if they don't visit often, if they get a pm (if enabled), perhaps they will notice the email and visit again.
