The concept can be done with the right ingenuity. For instance, I know of someone who has experimented with an add-on to the standard SL that provides a positive range of adjustment to the front-end without new UCAs, coils, struts, etc. I don't think we ever maxed it out, but it was run for a long time with a one-inch adjustment without a problem. I don't want to share his specifics (in case he wants to pursue marketing it), and I'm sure there's more than one way to skin the cat anyway, if you know what I mean.
