Firstly, a lack of availability isn't a reason to justify a longer routing outside of the normal rules. In the case of what you are suggesting, I think it will be a case of agent lottery. Some will be fine with it, others may raise it as an issue. It clearly isn't the most direct routing, but I don't think it is a ridiculous routing either. A little bit further, but hardly LHR-LAX-PHL either!
The only answer that counts though is that from the ICC when you try to book it. I'd certainly give it a go myself.
