Artificer Subclass Idea: The Tinker Tailor specialist

The idea is to make a more rogue like Artificer, but I really don't know what would work.

Ability Ideas include:

Allowing your magical tinkering items to function as pagers, letting you send short messages out to people who have them

A suit of clothing that either is armor, or disguises hides armor. 

getting not only tailors tools, but also either disguise kit or forgery kit.

Any one have better ideas, I don't imagine it would be too hard.

Embedding your armor with thieves tools.

Retractable grip, that can hold daggers or whatever. 

Creating a special weapon that lets you also do sleight of hand actions with every attack? 

Pocket scout that can pick locks, share it's view with you, record sound and other things?
