My initial thought was that this CJ led government will be responsible for drafting the constitution.
Then an election will be held and a new government will be formed which will be responsible for running the country.

But it looks like this CJ led government is only responsible for holding the election. Then the constitution drafting will be done by the political parties again.
Even if this is the case, it is a better step than the one we have now as it will create a legitimate government.
