Off the wall, but is it possible?

I've got a 2003 TL with 276k on the clock, and want the manual transmission.

I was thinking a k20 or k24 swap, maybe even an f or H series. I know there's the j32 cls swap, but I was just thinking. (no I am not a teenager obsessed with Honda 4 cylinders, this is a legit question)

I figure since our cars are built on an accord frame, an f23 should mat right up, and then building it beyond that. Just curious as to what you guys think.
