Problem is... While DNA modifications could be possible:
a) DNA modification in a style - Woah! We now have a hybrid between a human and a cat is not scientific at all.
IMO, That's against the spirit of game
b) Xenophobia. Character like that would have very hard time joining any team of mercenaries or surviving in any frontier station. Same goes for his entire race. People of that universe aren't shy to orbital bombard each other with WMD, guess what would they do with a race of the fast multiplying mutants?
c) The whole backstory creates one association: Hello
Mary Marty!
d) By amount of text you put in the backstory It looks like you expect to roleplay hard... But that game is about suggestions and turn based with sometimes weeks of game time passing between updates. Yep some suggestions may be in a form of character words, but this game shouldn't have several page long conversations.
e) The only thing I like is the specialty, drone\droid engineering can be rather fun addition to the game even if that makes our crew look like a bunch of nerdy engineers not mercs (small spaceships engineer, material engineer, military software engineer, now robotics engineer )
But it's not like we aren't going that way:) We got rather large workshop already. Chemical lab and med bay(biology lab?) are planned...
Also, when funds will allow, I plan to repurpose one docking bay into some kind of drydock, because cramping all tools in cargo bays will leave us without cargospace very soon
