I think this is a good idea, but there may be flaws.
This may cause lag.
Removing a bot and then automaticly adding it again might cause lag. Since the bot is going to get kicked it will have to get the min_bots command and will join again. If a bot is going to get kicked there should be a count-down of like five to ten minutes before automaticly adding another bot. This way it may become noticable, but I don't think CS players constantly watch a server for a half-hour before joining it. Plus this seems long and complicated to me and would take alot of testing to get this idea finished correctly.

If you want it to be more realistic I would suggest kicking the bots yourself and then add it or more back.

Also when having no objective would cause them to go around randomly, that's why you should always have atleast one bot on each team.

I don't think your ideas are bad, I think this one is cool, but I don't think it is neccessary. Since games are getting better and bigger, this one may soon parish within the next decade.
