So after deciding I wanted to play a Kaminoan, and after finding out they weren't just in Rise of the Seperatists but also in Fully Operational (for Engineers) and are depicted as being well-suited for Engineer, and being interesting species to play a rebel, I also stumbled upon Crafting and Droid Crafting in Special Modifications.
So, my GM at first was reluctant to implement cloning, primarily because it had no rules bearings, but... I've since brought to his attention that if Technician can use the crafting process to craft a Droid (an eligible PC species) capable of *combat* even, then it's not too unreasonable to change Droid to Clone, chassis template with genetic template, and a few other minor things, and I could legitimately strive to make clones. My GM is interested now.
Lastly, considering it makes sense, and they're in the book, Engineer *does* seem like a good fit. Now, Scientist seems like the most appropriate, but its skills and talent tree don't quite do the trick for a would-be cloner the way some other specializations do for characters that plan on crafting, especially droid crafting. So I'm considering attempting to homebrew a "Bio-Engineer" specialization that includes some similarities with the Doctor specialization for Colonists and other specializations that reference crafting directly or indirectly (with some similar structure to Scientist) and I was hoping someone had some advice for me.
