Ironically, very careful and deniable covert aid and diplomatic pressure would likely be more successful.

I completely agree. Material and technical assistance could be provided to a group of individuals from an opposing tribe who have been trained for special operations. This could be a feasible means for destroying or disabling Libyan aircraft, for instance.

This is a delicate time in both Tunisia and Egypt, and the only reason to consider involving them is to minimize the slaughter in Libya and the resultant impact on them of masses of refugees. But, if such actions could be successfully accomplished it could lead to greater regional stability, with three adjacent reforming societies. The danger, of course, is that the militaries in Egypt and Tunisia would have their power consolidated as ruling institutions.
