BBL 6-8 weeks after triple facial surgery (septorhinoplasty, brow lift and lip lift)? Planing on OPEN septorhinoplasty

I plan to have OPEN septorhinoplasty (to fix deviated septum and nose appearance) combined with trichophytic brow lift (that will both lift my brows and reduce my forehead) and also bullhorn lip lift on the same surgery day. Will I ruin the results of these 3 procedures if I have a BBL 6-8 weeks afterwards? Is 6-8 weeks enough time for full recovery? For how long after the facial procedures do I need to sleep on my back?
