Quickly running the numbers back in the spreadsheet, it looks like the Kensai 12/Monk 7/Rogue 1 would get more DPS -- 438 was the number I came up with for 0% Fort/no Transmuting, which represents about 10% more than Eladrin's Monk. And, heck -- even with the net -5 AC, it's still *good* AC.
Something else to consider is that Monk8 would get a damage die upgrade to 1d10 - not sure if that is better than the SA though...
