LE Picking up and placing activators

[Ironman5000]

Hey i'm playing around with a mod and would like to use a simple method of allowing the player to pick up and place static objects in-game, so can anyone help me out by explaining a simple method? For example

1. attaching a basic script to an activator
2. when clicking the activator removes it and adds a misc item to inventory
3. when clicking or dropping the misc item whilst in the inventory, removes it and places the activator in front of the player...preferably in grab state so it can be dragged around then clicked to finalise placement
4. The activator would be static/no havok

Something to that degree, I know there are already mods which do this already but they involve so many different things to make it work I just want a simple script attaching to a few things to achieve these results that's all.
