Custom Bounty Hunter/Assassination Droid [grendeljd]

Hey all. Seeing as my old request was deleted (over a year old and all that), guess I'm gonna repost it. Once again, I like your guys' work a lot, and would love to see someone tackle my first (or would it be second, now?) request.

Here's some background on the droid in question:

T4-K2 was a prototype droid created as a means for providing a discreet assassin droid to the highest bidder. However, the project was deemed too expensive to maintain the cost, and all of the entire line of prototype models were destroyed, save for T4-K2 himself. The droid, before this executive decision was made, developed its own personality and independent programming and, before the company could destroy him, he got away.

Over time, T4-K2 implemented various upgrades from his original form and became a professional-grade assassin and bounty hunter. However, he developed protocol functions to keep his primary programming discreet to his targets and those associated with them.

T4-K2, as his makers intended, serviced himself out to the highest bidder, and never became affiliated with anyone but himself.

Now, on to the appearance:

Mostly, it's pretty open. I wanted to make his overall appearance a mix of HK-47 from KotOR and Grevious's MagnaGuards. Not so much that he'd look like a combination of both, but rather that he holds the intimidating presence of a MagnaGuard (and/or HK-47 when he's actually fighting), but this presence is mostly a passive one unless he intentionally shows it off. In other words, he can easily pass himself off as a protocol droid (he fooled, basically, a "fortress" of Jedi with his appearance), but otherwise he's pretty intimidating to look at. I'd at least like elements from both droid designs to be seen in his appearance, but other than that the majority of his appearance is up to whoever wishes to take up the request. Additionally, and very importantly, T4-K2 has a personality, and I would like that to show. It has not been revealed yet, but it is possible that the droid has an AI programming.

I'm not picky about armament, kind of just "whatever works," as well as any accessories that he might have. So long, of course, as he doesn't wind up looking goofy. :P He's been known to use blaster pistols, and I'd like to see a blaster rifle if it fits the theme (if not, that's fine too). Otherwise, again, whatever works.

I think that's about it. I can answer questions if need be.
