What do you folks think of this (using Pathfinder Monk/Paladin core classes):
ASCETIC KNIGHT FEAT
Self-enlightenment and honorable service grow from the same ethical and moral basis. As a student of this philosophy, you have blended your training as a paladin and as a monk into one seamless whole.
Prerequisites: Improved unarmed strike feat, ability to smite evil.
Benefit: Your paladin and monk levels stack for the purpose of determining your unarmed strike damage, the extra damage dealt by your smite evil ability, your monk’s AC bonus and the duration/effect of your divine bond. Monk and paladin levels also stack for the number of uses for class features keyed to 1/2 your class levels but not for the effects or for the eligibility/qualification for such features.
Special: The number of smites, unarmed attacks and times a paladin may call upon her divine bond are not modified by this feat. The effect of the Ki pool or of the “Lay on Hands,” class features of the monk and paladin respectively, are likewise not modified or improved by this feat.
For example, a medium sized 3rd-level paladin/1st-level monk (a 4th level character) would deal 1d8 points of damage with her unarmed strike and +4 damage (+8 damage to evil outsiders, dragons or undead) on her successful smite evil attacks as a 4th level character. She gets no divine bond benefit as she is not yet a 5th-level paladin. If unarmored AND unencumbered, she would get the monk’s +1 to AC as if a 4th level monk.
Second example, a 10th-level paladin/3rd-level monk with no ability modifiers would have 6 uses of her lay on hands ability (rather than 5) but could only heal 5d6 points of damage even though she is a 13th-level character. She would not get any ki points as she is not yet a fourth level monk. She could summon her divine bond twice a day (as a 9th level paladin) for a +3 bonus (as an 11th-level paladin)--not 3 times a day, as a 13th-level paladin could. If unarmored AND unencumbered, she would get the monk’s +3 to AC as if a 13th level monk.
Third example, an 8th-level paladin/9th-level monk with no ability modifiers would have 8 uses (instead of 4) of her lay on hands ability that heals only 4d6 points, 8 ki points but still not have lawful unarmed attacks (granted by the monk’s ki pool at 10th-level) or be able to use the Abundant Step for 2 ki points (a 12th-level monk class feature) despite being a 17th-level character. She could summon her divine bond once a day (as a 5th level paladin) for a +5 bonus, not 4 times a day, as a 17th level paladin could. If unarmored AND unencumbered, she would get the monk’s +4 to AC as if a 17th level monk.
