is this at a network where you can't stack several modes together? like mode #channel +ooo nick1 nick2 nick3?
As far as exceeding the stackable limit, there should be plenty of scripts that use a @queue window which interacts with a timer to 'do whatever' at spaced apart intervals.
Also, you can enable 'own commands' in flood controls which should limit how fast it spams the server with these?
