I actually like the idea quite a bit, and I'm glad you thought of it!  Of all the brothers, I could see James being the least likely to have had a strong connection with their grandfather.  That being the case (and looking at the sort of guy he is) showing up in time to receive his inheritance is just the sort of callous move he'd pull.  I'd still post what he had been up to over those seven days, but I imagine it would be very...different from the other brothers' reactions.
