I doubt she would be violent.
Vulcans have learned to control their more violent tendencies and are beings of peace. Most of their more violent tendencies only arise during the Pon'Farr and if I remember the Way of the Kolinaar correctly (don't know where the hell it went to) only males go through the whole Pon'Farr thing (okay lets not get side tracked here) and Betazoids are naturally peaceful and serene. Bring her up on Betazed and she'd be quite normal I assure you.
Fight Naked? Where'd you get that idea. A mix of Vulcan/Betazoid wedding rituals perhaps?
A word on physiology, Vulcans are adapted for the harsh enviroment of Vulcan but if you live long enough in a different climate, the body will adapt...I think people take this I'm from a desert planet so I'm cold all the time thing a bit too far.
Mammals are by definition able to adapt their body to the most climatic conditions, some feel more comfortable in one climate than another but that's a question of upbringing not genetics and given enough time, you'll adapt...believe me I did when I studied in England...
Anyway just my thoughts...
Arise, arise, Riders of Theoden!
Fell deed awake: fire and slaughter!
Spear shall be shaken, shields be splintered,
a sword-day, a red-day, ere the sun rises!
Ride now, ride now! Ride to Gondor!
