Can I go from a DD/E cup to a nice perky B or C cup? (Photo)

Yes, I think you have a very good understanding of the "issues" at hand.  A very well executed breast lift/augmentation procedure will likely be necessary to achieve your aesthetic goals.My best advice: select your plastic surgeon carefully. Make sure that he/she has significant experience achieving the types of outcomes you will be pleased with. Then, communicate your goals carefully. If I were seeing you in consultation, I would ask that you communicate these goals in terms of goal photographs and/or computer imaging. Avoid the use of cup sizes as a reference point; this can be a source of confusion and miscommunication.
Working together you will come up with a good plan to achieve your goals. You may find the attached link helpful to you as you learn more.  Best wishes. 

The two ideal images you sent are of women with breast implants. They had a small firm chest prior to augmentation and then have a tight breast on top of an implant post op. They also have very little body fat. If your body fat was similar to theirs then a lift and implant could make your breast more uplifted and rounder in shape. Of course the trade off is a scar round the areola and on the breast skin. I recommend achieving your best body weight and then proceed with consultation for a lift and a implant. If you loose weight after surgery it may compromise the results. 

Hello dear!
Thanks for the question and provided photos as well.
Based on your photo, i think that with a small implant and a breast lift will give you a perkier, fuller and beautiful breast.
I recommend you to make an appointment with a board certified plastic surgeon to talk about your goals.
Good luck :)
