Ball joint flip does not improve wheel travel, only facilitates alignment. As for the bumpstops, be careful, they are there for a reason. The protect the CV shaft from impacting the lower control arm, I believe Uncle SAS has a story about that.
The SFIFS only works if you lower the front back down. No sense in forcing 3-4" of wheel travel, that is a waste. When I installed mine, I moved back to near stock height with 34s. Minimal rubbing, and some minor pounding/cutoff wheel in the front.
I used to be like you with the cranked up front end. Crappy handling and crappy ride offroad. Without a locker, you just greatly reduced your performance since you a very likely to have a front tire off the gournd (rock crawling, if for mud, I suppose it doesn't matter). I love the look of it jacked up, but its kind of like having fancy skater shoes,they don't really help you at all, just make you look cool
