Steve Cougan is the only name I've heard that makes me think "yeah, that could be ok."
I don't like Jody Kidd, I just find her annoying.
Part of the attraction of TG was the interaction between the hosts, they were pretty much three boys/mates pissing about. I'm not sure that would work if you add in a female presenter. I don't mean that in a sexist way, just that we all know we say certain things to our mates that we wouldn't say (or would tone down) in female company. Either way it will take time for the new host(s) to get used to each other. I suspect a lot of people will boycott the new TG in protest at Clarkson getting booted out, or simply cos they know it will never be as good. Actually, probably quite similar to how we feel about the prequels
