Would I still trust you, of course! (Great job on the radio the other day, by the way). I would be a problem if the powers that be started exerting an influence on the content of the blog or you felt that you had to neuter it yourself. The price of not being anonymous I guess (although you could start an anonymous blog as well ... ) But if it's something you want to do you should send in the form -- see if you get the interview. When you do get one you just go in and explain truthfully that you'll not take the job if you think it'll conflict with the blog. Maybe they'll go for that, maybe not. But I don't think you should bin the idea at this stage, at least see if they give you an interview. Maybe there'll be some other openings they might think you're suited for if they know that you're wanting a change. Basically, go for it, your readership will understand.
