Is it safe to combine HA (2 vials) & Sculptra (1-2 vials) for gluteal improvement?

Is it safe to combine Hyaluronic Acid (Deneb) (2 vials) and Sculptra (1-2 vials) for gluteal improvement? I need to cover some irregularities after butt implant . I know fillers are not the best solution, but I need a temporary solution until I can get surgery. I have no fat to harvest, so I don't have many options (repositioning at least the left implant and lifting some extra skin around the gluteal fold in right side). Thanks
