That depends, I guess, on what kind of riding you'll be doing while you have the bike. If its a lot of stop-and-go, then you might appreciate flat-footing more. However, there are limitations in bikes wrt to size so your options are almost negligible. My wife has a similar issue with seat height. One thing she did to improve that was to get boots with a bit of a heel. It helped her keep sure-footed on the pegs too, since she doesn't keep her feet "race-ready" and doesn't really need to.
Besides getting a different seat, there are usually "lowering links" that can be put in to lower the bike. At the same time, the forks are usually dropped so that overall characteristics of the bike remain per the designer's intent. If you're not mechanically inclined you'll want the dealer to do this for you.
