monk1/wizard4/enlightenedfist10/abjurantchampion5 gets you 17 CL for 9th level spells, 14 BAB, and 11th level monk abilities
Alternatively you could go bard1/paladin17/monk2 with the able learner, devoted performer, initate of milil, asceitc knight, battle blessing, power attack, and divine might feats so you sing about how you're kicking the guys ass as you're doing it. I'd recommend the overwheling attack monk variant from UA/SRD for the power attack and improved bullrush feats to set you up for divine might and shock trooper.
