Would a higher CC implant allow me to achieve a more lifted appearance without actually having a lift?

You can achieve an illusion of a lift with an implant in a dual plane positon to some extent and may be a small crescent lift just to pull the nipple up. If you are hesitant, you can so the implants first and see how it looks after about three months and if you are not happy, you can then do the lift. If you are happy, then you don't do the lift. They don't have to be done at the same time.

Hi, thank you for sharing your question. 
You are a great
candidate for breast augmentation with a lift. Implants will give you the volume and upper pole
fullness, but based on your photos, you would still have some sagging. The lollipop scar may be needed to reposition the nipple and give the appropriate skin tightening. The specific implant size and shape should be
determined together with your plastic surgeon after a formal evaluation
of your breast tissues. 
Consult with a board certified plastic surgeon to review your options. I hope this helps. Best of luck!
