I haven't put to much thought into mounting bumpers on this frame since it's just an offseason prototype, but I think what we'll do is something similar to 148's 2011 bumper system; put 1" hex standoffs in the corners and then use a uni-body bumper frame and bolt it to those hex standoffs. I'll CAD this and post a picture of it.
Here is a front view of the bumper frame and hex mount:

$60 for an entire drives worth of pulleys isn't crazy at all.
