Israel would probably be fine with a moderate government in Iran. A moderate Tehran doesn't encourage Hamas and Hezbollah to randomly lob rockets into Israel.
Even if Israel disagreed, a moderate Iran balances Israel in the region. An Iran that has beef with literally every single one of its neighbors other than Turkmenistan cannot provide that balance.
Maybe, but I think they are genuinely aiming for a failed state.
Israel is a state with a political apparatus that is predicated on providing security. That apparatus needs a persistent (but non-serious) threat to remain in power. I think best case for that power is to have a number of failed, weak states in the Middle East that occasionally launch relatively impotent attacks against Israel. This would also have the side effect of giving hard-line elements in Israel the enough justification to expand their borders and continue ethnic cleansing (e.g. what is happening in Lebanon right now).
Well, is that better than Israel and its relationships with its neighbors?
Yes. Tel Aviv retains solid security relationships with Jordan and Egypt. And it trades with its region [1]. On a ranking of hegemonic pests, Iran is way ahead.

> Summarising the Israeli government’s position, Citrinowicz said: “If we can have a coup, great. If we can have people on the streets, great. If we can have a civil war, great. Israel couldn’t care less about the future . . . [or] the stability of Iran. > > “That is a point of difference between us and the US. I think [Washington is] more concerned about nation-building and threats to their regional partners,” he added.
I don't think they would be happy having a moderate government that could still evolve Iran into a regional leader.
Pre-war, Iran had good relations with Qatar and Oman. Also with Pakistan. And Armenia. Their current relations with Iraq are also OK.
They have problems with Saudis, Bahrain, UAE - exactly the countries with extensive US military bases. No surprise there.
And Iran has not (prior to being attacked) attacked any of their neighbours.
The only two neighbouring countries Israel does not have problems with are heavily-bought Jordan and Egypt (Israel still attacked them prior to Camp David accords).
To any non-ideologically blind person it is obvious who is the one stirring the instability in the middle east.

It is working on making itself larger cleansing whole areas around it and settling it.
