He'd fit in fine, I think. Everything's going to be a bit weird anyways.
And don't worry Kris - you can still find one of the items, even if you won't be completely taking part in the plot. Or, if you can, so much the better
As far as what the objects are, they're all either going to be slightly magical items (Like the bottles Rachel picked up and passed Reinholdt) or trinkets, like bracelets, plaques, and necklaces. In fact, some of the trinkets might be magical, but they're not going to be majorly magical - minor things, at most.
