Hub and splines

I've prepped a good chunk of my old and new parts. My question is knowing that my old hubs and splines are wore out is there any reason to keep them? Could hubs be switched from sides and repressed onto different wear pattern splines and achieve the right clearance? I'd just as soon throw them in scrap pile, I just don't want to regret it later. Thanks

If the splines are worn to the point that you would not achieve full sprocket contact within the recommended press load and end clearance I would consider them junk. Only on an emergency basis should reuse be considered.
