Why not do something origninal with your own ideas.... Here are a few that I could think of
1, Dihedral on demand - Can change dihedral during flight
2, Sweep on demand - Can change the wing sweep angle on flight
3, Or may be something like a transformer...
.. I am thinking of a plane that could curl its fuselage on to itself so that it could land like a rolling donut.. Just a concept no solid design realized yet.
Subbu, its time to improvise and I am sure you have the skill.
