Haha! Sorry Bargoo, that's too funny
Whether your goals re unrealistic or not isn't for me to judge, as there is huge variety in metabolism, frame size, and generally happy weight territory depending on the person. But if you have had children or are approaching peri menopause I'd reconsider your goal, if only because more mature female bodies tend to sit at naturally higher fat levels than they did earlier in life, even in peak fitness.
At your size weight drops slowly, so even half a pound a week would be incredible sculpting progress for many women. With that in mind, I'd say you need to do nothing but be PATIENT with the extra pounds and keep doing what you're doing. If your body can go that low persistent calorie deficits will bring it there eventually, unless other factors are at play.
Please also consider strength training or bodyweight workouts like Callanetics/TTap/Pilates if you don't do them already. You can get immense results at the SAME weight from body recomposition with working out. We're not talking burning calories, though that happens as a byproduct, but building muscle mass and increasing bone density. Reshaping, as it were, is best done with heavy weights and full range of motion workouts (squats and lunges are brutal and excellent, all at once, for those trouble female areas).
This is just food for thought, but your best bet for achieving such a goal weight, or at least the shape you desire, is patience and sweat equity with lifting heavy stuff!
