I've found myself in this conundrum once before - though thankfully it had more to do with mana addicted Elves that the plot of the game itself more than suited - However, I'd like to weigh in just a bit.
Roleplaying a plot filled with intrigue is something I don't see very often, wherein the characters -will- lie, cheat and push their way to the top - I would suggest anyone you start involving be informed ahead of time that your character is going to lie and do some shady under the table stuff ahead of time, as I've run into the issue of people accusing me of meta-gaming my own character by claiming that I should have mentioned he had lied earlier on to justify the disadvantaged situation they then found themselves IC. (How I'd do that, I don't know. Maybe I could buy a blue police box? I thought it apparent considering my character at the time was a well established politically savvy antagonist.) I say this if only to help you avoid unpleasantness down the road, and to be generally courteous to your fellow RPers.
The lore itself, at least as it is demonstrated during the main scenario quests throughout Coerthas as I've seen, doesn't do much to discredit the idea of pseudo-political power struggles between history's most debaucherous caste. I would suggest using the lore to set the boundaries and your own understanding of crime and punishment if you get caught IC to determine where you might progress from there (or perhaps, to establish a pretense to frame your would-be adversary.Â
)Â
When all else fails, a little google search for comparisons to the real world never hurts either, so long as you find a way to either keep it lore friendly, or revamp it that it would better suit Hydaelyn. If you get this idea off the ground, I'd love to see where you go with it and hope this takes you to some awesome stories. Feel free to add me (Stroud Forscythe/Char Lohengrin) if you would care for a few casual encounters with someone that does a character like this regularly - I personally look forward to seeing your character development.
But to answer the immediate question posed at the outset; It's never really been a stretch to make assassinations to one's own gain - So long as they don't conflict with any of the established characters, or other NPC's outside of those conceived of our own mind - I don't see much issue with that in and of itself so long as it isn't done in the fashion of 'A walked up to B and shot him in the face point blank in front of a thousand people he had never met before and then got away with it'. But as the above mentioned - Ishgard is full of some unpleasant voices, reinforcing my opinion on the matter.
