First suggestion: don't use the pre-made chars in the book, not to play with or as point of reference.
Make a rigger, invest a few points in Cha and social skills, get tailored pheromones (, have a skinlinked microcrawler with Improved Sensor Array and upgraded camera sitting on his shoulder)* and run Empathy Software, or get an emotitoy thing.
Alternative: make a dronomancer (Technomancer specialized in drones), they need high cha, which you can use for the face part too. Some ranks in social skill group, maybe a First Impression or something and you got a face. Toy and or empathy software can be used to max it out too.
"By the by, is it legal to mount a rifle with an underslung grenade launcher in one mount?"
Don't see why not.
As for the Lynx, as powerful as it is (or can be), keep in mind that that thing is about as large as a small van... it will be difficult to take with you on 'runs.
