Moving return fitting in p.s. pump

[mc1984ss]

Unfortunately the return fitting on my p.s. pump hits the engine block. I've weighed my options and moving the return fitting seems to be a cheap way to go and I can convert it to AN right away. I have attached a picture showing on the reservoir where I would like to weld a bung in.any reason I can or cannot do this? Not sure if there is any reason to not return it here. Thank you in advance!!!
