Ok, first I apologize for butchering your pic. Second, I might be bit of saturation junkie.
Anyway, dont shoot me please.
Capture One 7, bit of structure boost in PS. Btw. why you cropped it? It works nicely in center composition..
Bit of personal input now.
You try to make one camera look like another. In theory its possible, in practice I guess custom made ICC is needed (or in case of Adobe, DNG color profile). Another "problem" is that you are probably used to high quality of Zeiss (Contax G) or Voigtlaender lens on NEX, which are near impossible to mimic. And even tho 24-70mm f2.8 isnt bad lens, its not somewhat spectacular either (just my opinion). Plus theres thing called color transfer, which is pretty much how much of each wavelength goes trough lens and how much is saturation lowered in each of that wavelength.
Samyang lens are excellent in this, Canon much less. Plus 5DMK2 does have quite a bit of green in red channel, while NEX doesnt have so it has (in theory) better color separation. My opinion is that one does need to have great colors at start, to work with them later, but you cant "make" those colors, if they are not there. From my experience, right color profiles do wonders sometimes, but nothing is almighty.
Obviously I dont know how much you know about this stuff, if you already know this, then Im sorry. Plus there are guys on FM, which are most likely much better in this then me.
And as I said, its personal input.
My main point is, that your pics are pretty much fine as they are. 5DMK2 is simply different, not much problem in different look, when its still good picture. If you really dont like it, then you know.. A99 might be good solution.
Kinda like this one.
