People were really only 5 manning Kara once patch 3.0 hit and all classes got massive DPS boosts. Before that people were certainly taking multibox teams, along with others, and doing kara, but I don't think anyone was really 5 manning it outside of perhaps a few Sunwell geared people.
Naxx will certainly be doable like this but it'll take a while for people to "outgear" the instance -- ie once you have some people sporting season 7 (or whatever) or T9 they will probably so outgear Naxx that it'll be a lot easier.
BTW its still worth doing kara 1st boss once a week, I do it every monday. His mount dropped for me yesterday, hopefully i'll get 5 in the coming months :)
