The upper a-arms do make it possible to set the alignment with the keys cranked way up. Stock upper arms would be too short.
That does not address the lower ball joint being beyond it range of motion. It will be bound to the inside and prone to failure. Add to that the cv-angle , tie-rod angles and the mix just does not play well.
There is plenty of room for meeting the maximum z- height with the stock keys. You will be at the max for aligning camber and caster. Still it is about as far as you really want to go if you want some decent ride , handling and longevity from the front end parts.
If you really need more than the 2.5" (1"-1.5" key adjustment and 1" tire size) the MML does, it would probably be wise to consider going to a drop diff lift or SFA.
