Potential issues...
** spoiler omitted **
Okay, so I went through and I think I got most of the powers required for my gear. I had trouble finding something for the Traveler's Any-Tool. Don't think there's anything that mimics Major Creation at all, which I suppose makes sense. If anyone can think of something that'd come close to that spell, I'd be extremely grateful.
For the skills-do I get any of those as class skills? I feel like alchemist should at least net me Kn (Psionics) and UPD, seeing as it also gives Kn (Arcana) and UMD.
As for vivisectionist flavor, I absolutely agree-slicing people open to see how they tick works for some characters (like on Blekk!) but here? Ehhh. He comes from a pirate family, chances are he's seen his fair share of guts and stuff. It'd be enough to give him a decent understanding on where to hit someone where it hurts (AKA sneak attack).
I think I got everything else, if you want to work out my background over PM or something, feel free to get in touch. I'm open to anything, background-wise. I made it kind of vague slightly on purpose so that it'd be easier to fit into the campaign. Can't wait to get started! I'm excited for this.
