I've been thinking a Muun trader or quartermaster might be an interesting character, but we don't have Muun stats yet. They are described as very intelligent, tall and skinny. They have a fascination with numbers and their native language is almost binary in nature. They love money, and are very good with it. They have three hearts, two of which are voluntary muscles, but not much is written about how they benefit from the extra circulation. This is what I've thrown together.
Brawn: 1, Agility: 2, Intellect: 3, Cunning: 2, Willpower: 2, Presence 2
Wound Threshold: 9, Strain Threshold 11
One free rank in Negotiation, may not start with more than two ranks in it.
Mathematician: an extra boost die in any check in which numbers play a significant role. (Negotiation and Astrogation would get the bonus every time. Mechanics, Computers, and Knowledge - Education might benefit from it every once in awhile. Gunnery might benefit from it in a case of indirect fire weapons. Knowledge - Warfare could benefit if the check was about troop strengths and things like that.)
Accountant: Begins with an extra 50% of credit allotment, including extra credits gained from taking on more Obligation or less Duty.
Starting XP: 90
to all Negotiation and Astrogation checks.
