I don't think that would work... As far as i can see, mean mod only supports two bots a at time... but the readme is outdated, so it might have changed. I've made a topic asking about it.
I doesn't seem to work when i change podbotmenu to poxbotmenu with a hexeditor... but maybe I'm just doing it wrong. Fortunately the other advice about pb addbot and addbot works fine
