Would almost be best of both worlds to delete DPF and EGR to open up the engine breathing yet retain SCR/urea injection to take care of the smell/NO
- I wonder why that hasn't been done before, I guess because people don't want to be bothered with piss injection -

I'll second that.

DEF is cheap. I've got no problems topping that up, assuming SCR functionality can be maintained while deleting the DPF and re-circulation of exhaust gas though my engine. At the end of the day, I'm not trying to be green, but if I could curb some of the output while opening up the performance and longevity...it would feel like a happy compromise.
