hey man-
first off ya got the wrong forum! go to remixing for questions about, well, remixing http://www.ocremix.org/forums/forumdisplay.php?f=12
second of all, when it comes to arranging a remix, the rule is generally to try to keep around 50% of the music true to the original track, and 50% new material/"arrangement". Just make sure there's enough zanarkand in there and as far as I know you should be fine in terms of arrangement Just make sure the zanarkand theme is recognizable.
good luck!
