Therefore we would need to replace the pump with a flat piece of stock that holds a very strong, very well-mounted stud akin to the stud or boss on the idler. I think the design of the pump, coupled with the stresses and slaps of a timing belt, may just be too much.

For those concerned about power loss, maybe the answer would be a shaved impeller for applications where high RPMs are the norm. An electric pump would take up the slack while sitting on the starting grid or in the pits. For a daily driver I would think it's best to leave well enough alone except to make the unit generally more robust.
