Random Join/Leave mod?

[XTroid_Hunter]

Just wondering if there was a mod or whatever out there which would randomly have bots come/go from games simulating how humans tend to come/go (ie: the more the bot is getting totally destroyed the higher chance they will bail out, the more they are owning the more likly they will be there again the next round)

Preferably with a setting to limit how many bots will join/leave so that the bot number you set when creating the match is kind of like the adverage.

thanks :)

Don't know about there being one such mod or mutator out there right now, but I'm sure something like that could be done.
