I don't know. It depends on the available libraries on the N9. The requirements for Maep are glib, cairo, gconf, curl and soup which are quite standard. The UI part should be adapted though because the QML components for Sailfish are different from the one of the N9. In addition, the binding of the cairo stuff with QML should work, I tested them quickly with QT4.8 before starting with QT5 for Sailfish. The GPS handling should be adapted also because currently, it's using QPositioning which is part of QT5.2.
