I'm really surprised warn told you to run the winch that way. I've never seen it done that way, but from an engineering standpoint and how metal stresses makes me cringe. For some that don't know, metal tears before it compresses. When running the winch in the normal position, the four mounting bolts act as huge sheer pins that don't sheer. With having the winch pull the line across the top of the drum, the load will be transfered to the heads/shanks of the bolts, and hopefully, not tear them off. Say you have a 9500lb winch, you're putting over 2300lbs of pulling force through each bolt, but by design it's putting the immediate load through the rear two bolts. That's over 4500lbs each. If Warn says it's cool, I'd still be against it, just due to the stresses on the hardware. Say one let's go, or two, then your winch is trashed as well. I'm all for outside the box, your fab work is sick! Design gets a A+ from me for all the items you're incorporating into this thing, I'm just beyond sketched out by the load over the top of the drum, and the hardware. Anyone else visualize what I'm spittin?
