For an inkjet paper to work, there are roughly two (AFAIK) approaches in common use. Well, really just one, but used to be two. In the early inkjet days, this was a colloid coating, for instance gelatin or a gelatin-like substance. Presently, pretty much all inkjet papers have a microporous PE coating - essentially a very thin, flat plastic sponge. I'd be surprised if this paper were any different. That there's a barium sulfate layer underneath that plastic liner is apparently great for marketing purposes. Otherwise, it doesn't mean much as far as I can tell.
Coating inkjet papers tends to be very different due to how they soak up the liquid. You generally can't 'push around' a puddle of sensitizer like you can do on most normal papers; instead, liquids virtually disappear instantly into the surface as they hit it. This makes even coating more challenging to accomplish. There may also be additional issues in processing, clearing, fixing etc.
As always, give it a try; see how it works. But I don't expect this to resemble a 'proper' baryta paper like we're used to in the darkroom domain, especially not in how it handles alt. processes.
