I want a more heart shaped butt - is Aveli and lipo of hips and fat pockets a good option?

Hello, 63 yr old. recently lost 40 lbs. Still working and can’t take too much time off. Don’t really want a big butt but want to do the minimum to give mine a heart shape and not so square and flat. Tried 4 sessions of emaculpt and it did nothing, 3k down the drain :(. Working out more but with no results. Bulk of my budget will be for tummy tuck and breast fat transfer.
