Shane,
Are you crazy?
I wouldn't try that route until the fall. It gets full sun all day.
As for ethics... I don't think people would like you to pull stuff off intentionally.
As for bolts, they don't get replaced since they are part of what makes the aid fun. The only ones that are acceptable are anchors (e.g. on a free route on El Cap at the belays). People do "cleanup" the fixed junk, which is essentially pitons, heads, and it gets a little shady when it comes to "fixed" cams and nuts.
As for Bridwell... Brad cleaned up a lot of the bolts and it should be good to go for free climbing.
If I tried it, I'd just like to start from the ground and see what happens. Just wear a helmet and stand aside for the belay.
Who knows, if my carpal tunnel surgery would heal and I can get into shape, I could try to onsight it. Or I could get the flash after you do. That is this fall or winter.
