Here are models I made using Google Sketchup 8: http://imgur.com/ZnUe0q3,9p14X9v,AKMht6b,hVSaq94

My idea for stats is:
The House Call
Level 5 Invisibilty Phone
+20% faster cloak regen.
On random occasions when cloaked the phone will ring for 10 seconds then making enemys aware that you are close but this will also highlight the whereabouts of all enemys so you can uncloak safely.

What are your ideas for stats?

I'm not expecting this idea to become real as I have hardly any modelling experience, but if you do have experiance and you like my idea I would be more than happy for you to make a proper model and put it on the workshop.
