I very much doubt that would happen. Sony normally isn't bothered with the people who improve on their software using their icons, fonts, etc.
PRS+ uses Sony's icons - they were never asked to cease . I think, as long as you don't try to distribute the product on the open market, outside "the Sony world", you are fine.
Having said that, if people do go ahead and produce a new set of icons (as long as they are obtained legally, and meet your requirements), it would be great if you can manage to utilize those. Would be even cooler, if one could select which set of icons (skin, GUI style) to use. As long as the APK still fits in the puny /data partition on the reader...
