Is a 3rd scar revision a good idea for me? Or should I just have filler or do nothing? (photos)

Hysterectomy scar wasn't pretty (surgeon used glue). Scar revised by a plastic surgeon - ended up wide & keloid - so kenalog injection. Scar still looked bad so 5 months ago I went to a 2nd plastic surgeon (in different state now) and had 2nd revision. Again, wide and now more keloid than before. Surgeon injected kenalog - caused a large dent. This surgeon has offered to revise again and do a little lipo. I had ab lipo 3 years ago. I respect this surgeon but worry about it ending up even worse.
