Sorry to hear about your bushing issues. I actually changed mine out but I soaked the bolts with rust penetrating oil for two days while I swapped out my front end struts (following your great step-by-step post!!
If you're just holding on to the Compass for another few years, I guess you could weld the brackets after swapping out the bushings. I'd be worried that the bracket isn't clamped tight enough to hold the bushing in place while you tack it otherwise you'll still have that play once you start hitting rough road. But I'm sure you'll work it out.
Good luck with whatever you decide!
