modified lca's (crazy?)

[vegadesign]

im keeping drum in all 4 corners so no drop spindles are availible
im trying to stay away from z'ing my frame till way later


the front is bagged with plates and cups
cups are 1.5" and there is already a little bag rub so i dont want to go lower

i was thinking of chopping the control arm up and cupping it but...
moving the balljoint up 2"
basically z the control arm

does this seem crazy
iv got plenty of fab skill to attempt it but do you think it will mess up the geometry and performance of the suspension???

im thinking that if i do all this it willl get me to lay crossmember( an extra 5")
