For the reasons you give I think it's a very strange choice, particularly to make it so early. Top three in the Supreme, and none seemingly interested in what could be another weak Champion Hurdle. It would have made far more sense to take in a 'trial' and then decide a plan. Imagine if he bolted up in a Fighting Fifth? All that said, and I know he eventually changed his mind about Kabral Du Mathan, I don't get the impression that Skelton is someone who finds it easy to change his mind. I think the price for the Arkle is even worse than it was for the Supreme. Had he targeted the Champion Hurdle it wouldn't have surprised had he been near enough favourite for that as well.
