Would liposuction alone reduce the size of the mound?

liposuction plus internal heating with BodyTite  or renuvion will HELP but likely you need skin removal/pubic lift and I would suggest fat grafting to your penis along with suspensory ligament release to extend your penis at same time.  Best, Dr. Emer.

It has been a practice for number of years to reduce volume of mons pubis in order to visually and functionally elongate penis. In your case, aggressive  liposuction of the area would definitely create significant improvement. However, whether liposuction alone or in combination with skin excision would be most beneficial can be assessed only on the basis of in person consultation. Good luck.

I appreciate your concerns, and if diet and exercise fails to achieve your goals, liposuction of this region is an extremely reasonable option. This area has well-defined fat which is amenable to micro liposuction, using small cannulas to expertly contour the region. If skin is lax within the region, local skin excision can be performed simultaneously. Consult with a board-certified plastic surgeon in your area for a full evaluation. Good luck.
