i use a similar combo, but with the elite stormforged leggings (or whatever they're called now--the skirt with the lightening bolts and transparent bits).
i have them dyed a dark purple (black + purple iirc), and this mixed set matches identically in terms of shade. also have the standard sunspear leggings and elite ice-forged leggings. i feel stormforged has looked best so far.
