Once you exceed your Max Drag heavy load, you should by Immobile. completely, and taking damage. Fixes that issue right off the bat.

Yep, something like that has been implemented.
I've tried smithing, smelting, gilding, woodworking, carpentry, hide curing, leathermaking, and leather boiling with Torgan. The only "buff" ever available to me was Rage, which only affects Str and Con, and then not even for long compared to a true buff spell/potion. I've mastered smithing, smelting, and gilding. I've gotten pretty good with carpentry and woodworking, and am a bit n00bish at leathermaking simply because of the hassle of getting all those hides together. If I can make it without buffs, so can anyone.
Torgan has something like 10 magic bags, with the majority of them being the -60%. This is how I can have multiple suits of armor, always have at least 5-10 ingots of silver on me, and more weapons than I'll need in Torgan's life and still have room to spare. And yes, only craft what you know you can sell.
The only thing I see this doing is that you can no longer fill your entire inventory up with metal ore, and try and make it back to a smithy. Which I think is probably a good thing since there was no logic in it. (Even though I've seen some smiths RP having a wagon or cart with them...)
As for corpse carrying, they too fit in magical bags.
