I think you missed OP's date on the B1's. His year was the last of the wood core versions, quite suitable for advanced and up, quite good in the east (at least mine were), and beloved by bumps skiers (suggest a search here or go check out old reviews at online sites). You're thinking of the more recent B1, which was foam core, cheaper, and yes, definitely an intermediate ski. Also disagree with your characterization of the 8000 as an "expert" ski; a lot of intermediates use them happily because the ski is so forgiving, especially the more recent iterations with a wider shovel and slightly softer flex (again, suggest a search). They're a very popular rental ski out west. Not usually the hallmark of an expert ski, although certainly can be enjoyed by excellent skiers because of its versatility and solid construction.
My main point was that he already has a nice ski, don't think going 9 mm wider to similar construction will make that big a difference. In fact if the 8000 has a weakness, it's grip on ice. And the comparatively long turn radius is not great for smaller eastern slopes. So he may be actually losing performance.
