You mean Diplomance him? Since charm inside an AMF is so ridiculously inefficient it's comical
Diplomancy it is.
Ultimately you would just cost yourself a mook, though. Any AMF countermeasures would still go into effect, regardless of source. Not to mention, all of us that are fully paranoid persist Invoke Magic, so you'll have to lock down not just our area, but the entire area a Dimension Door can reach (which is quite a lot, especially with CL boosting).
EDIT : Take a look at the mage killer war weaver I posted in the war weaver guide. Duskblade 3 plus Arcane Archer 2 with 9th level arcane and divines and BAB 16@20, strong saves, excellent buff capability, and Dispelling Screen just like the real spellcasters use, all in all they'd at least fight em to a draw.
