Sure it's possible, but it may look stupid. You can go 1" or maybe 1.5" up front w/ just a TT. The combination of shackles and AAL's will lift the back 3-4" (depending the combination of parts you use).

If it were me I'd just get one of them for now. Buy the other when you have the money for the new UCAs. You should also consider adding Bilstiens to your mod list in the future.
