I love me some PVP, but...
Many good reasons why it might not work out very well have been stated by others already, there's the possibility of class/job imbalance to consider too. Some jobs will likely be flat out better at 1v1 PVP than others. For that reason I see using /duel to decide RP conflicts as something that would only be suitable for a very limited amount of RP situations, and only if the outcome is acceptable either way for both parties.
What little PVP occurred in FFXI was totally dominated by Redmage/Ninja if I recall correctly. Many other job/subjob combos had no fighting chance against a Redmage at all.
