Would Roundup QuikPro also work? I assume so since the product description says there's no residual soil activity.

I would stick with the gly only products. Diquat is mixed in very often to give a visual appearance of plant damage faster than glyphosate (to appease impatient consumers itching to write a bad review), but it isn't actually any better. In fact it could make it worse if the diquat triggers some undesirables into dormancy and hinders the glyphosate's ability to be absorbed into the plant. I have also heard things about diquat being no bueno around trees, but that could be BS.
Edit. Don't get me wrong, QuickPro is still going to murder a lawn, so I would say if you have some packets on hand and want to use them up, sure, smoke em if you got em but if you are buying product to do a reno, stick with the cheap gly concentrate.
