Re-taking Gaza: a bad idea?

For the past weeks, an increasing number of voices have been expressing the need to re-take the Gaza Strip as a solution to the recent rocket barrage.
Hamas is weakened and removing the group from power would be easy for Israel, according to Major General (Res.) Amos Gilad. There isn't any doubt that the IDF is more than capable of taking Hamas down, despite all the threats that the organisation has made over the past weekend; however, what is the plan exactly?

"We tell the enemy and (Foreign Minister Avigdor) Liberman who is threatening to reoccupy Gaza that the time for your threats is over, (...) Any aggression or crime or stupidity you commit will cost you a very high price." - Ismail Haniyeh

It would be interesting to know how Mr Haniyeh intends to concretise those threats given the blows dealt to his organisation:

1. The seizure of Klos-C (carrying the famous forty 302-mm heavy rockets)
2. Hezbollah's involvement in the Syrian conflict (which is causing the group to be attacked at home, in Lebanon; and most probably decreasing its availability to come to Hamas' rescue in case of a disturbance).
3. The Egyptian banning of the group, the seizure of all its assets and the block of 90% to 95% of the tunnels it used to smuggle weapons from the Sinai.
4. The outbidding strategy carried out by the Islamic Jihad (that vies for the control of the Gaza Strip).
5. The discovery of two major tunnels into Israel, by the IDF (one in October 2013 and another one last week).

In light of the present conjuncture, it is dubitable that Hamas is in position of making others pay "a very high price".
But going back to the original question; what's Israel's exact intention regarding Gaza:

a) Does it intend to depose Hamas and hand the strip over to Fatah/PLO (so that the Palestinian State can finally come into realisation, through the existence of a physical territory)?

or 

b) Does it intend to re-occupy the strip until a peace agreement is signed with Abbas and his cronies?

I must admit that I would be more inclined to support option A (a demilitarised Gaza Strip; administered by PA, with the maritime blockade lifted and all), as a nth opportunity to the Arabs - to see if they could actually build a sustainable state and live in peace alongside the Jewish State. Certainly, this would imply replacing the Oslo Accords with a more viable conditional agreement.
If the PLO, the sole representative of the Arabs of Palestine, would fail to comply - and the terrorism would proceed - then the international community would see Fatah's real intentions and, be encouraged to support Israel's necessary actions (to achieve peace, once and for all).

If Israel coordinates the re-take of Gaza with Abu Mazen, perhaps it won't be such a bad idea after all...
