Alexis, While a Conjurer Monk would be difficult to pull off its possible the problem is your mixing a pure Magic Class with a Physical Job.
Though in my system as I tried to describe it, when a Job is attached to a class, certain abilities for that class itself change based on the job. In the Case of Monk being laid over any class you could have it so that Skill 1 (Spirit Dart in the case of Conj) Augments and becomes a new ability as long as the Job Is in place. For Monk this ability could be anything from Chi-Blast (Representing the oldschool Monk Ability and using Vit/Mnd for its damage instead of just magical stats) to Hefty Swing (A basic physical attack that deals damage based on Vit not Strength)
As well The Skill 2 (In the case on Conjurer Tranquility) Turns into the Job's specialised "Ohshitbutton" skill. For the case of Monk this could be "Hundred Fist" which fills your Stamina Bar up to 100% and causes your character to automatically attack with a basic physical attack repeatedly at a fast rate with a x1.5% bonus to damage for the duration that it takes stamina to return to 0.
