Would it have been effective?

Not in the situation Germany was in (lack of ressources, war situation etc), but then again, nothing would have been effective because of that...
Still an interesting topic and I recommend this video if you want to know more: https://www.youtube.com/watch?v=B7Q92V5hK-c
Might have been good against bombers, but then you're just going to have smaller, nimbler fighters going low to the ground and strafing the missile sites. This isn't like modern SAMs where it can lock on from beyond the horizon and track the plane through chaff and evasive maneuvers. It's more like an upsized Stinger.

Not in the amount of development time they had, and not while fighting for resources with all the other Super Secret X Weapons of Ultimate Doom.
