People that are more frum than you are usually not any less “normal” than you.
The one reason we all love the coffee room is to hear and argue and discuss all the different views on almost anything you could think of.
Splitting it up will make it much less interesting and not as entertaining.
I don’t think you have to split it up, people just have to understand that not everyone fits in the same mold as they do and its not that terrible.
And yes the super frum that are bored at work with internet should be here better than anywhere else.
