YES, changing the gullet will help fix the front of the saddle. Put in the next wider gullet and evaluate the fit again.
If you had a fixed tree saddle (without a changable gullet), then no, you could not fix it at all. You would have to sell it and buy a new saddle. However, with a changable gullet saddle, you can change the front of the tree to help the shape. A good saddle fitter with Wintec experience should be able to help adjust the padding in the panels as well, to tweak the fit even more. Or, you can have the CAIR panels replaced with flocking for a more traditional re-fitting.
