...yes, but just the 16mm pancake. Do you think that the bokeh effect would be better with a 50mm -75mm equivalente on the NEX - M-Hexanon? I mean, maybe I should try to find a 50 M-Hexanon instead of a 35 or 40mm Voigtlander...

You get more blur with longer lenses. But of course, you get a more narrow field of view too, with longer lenses.
Lenses of 50 mm and below just are not bokeh wonders, not even the Canon EF 50mm f1.2 L USM has really smooth bokeh. To me, field of view is most important in focal length choice for a photo, and the quality of bokeh and amount of blur secondary. The field of view makes the image, and the bokeh is about how that image gets rendered.
Look at for instance my close up images with the Canon EF 35mm f2. Its bokeh is not excellent, there are almost no 35mm lenses with excellent bokeh (maybe two real exceptions, both of them being a Zeiss). Almost noone uses that lens for what I use it for, 35mm lenses are seen mainly as "full frame street photography" lenses. Most people use 90-105mm macro lenses for those kinds of close ups. BUt I happen to really dislike the field of view of that class of macro lens on APS-C... it is the field of view that gives my photos their character.
And, to be fair, the bokeh of the lens does not look half bad at all, in my images.
Longer lenses can get more blur, and usually also more pleasant bokeh, but their use is more restricted... a 75mm lens will mainly be used for portraits (head or bust only). a 40mm will be more flexible in its uses.
It is for you to decide upon a focal length, and what you want to do with it.
I'd get a 20 to 24mm for street photography/snapshots, that 40mm for a versatile "standard prime", and only a longer lens (like 75 or 90mm) when you want to shoot portraits.
What is it you actually (want to) photograph? It should point you in certain focal length directions. If you don't really know that yet, you can not really go wrong with that 40mm f1.4 "almost standard prime". Makes more sense on 1.5x APS-C crop factor than the awkward 50mm lenses, in my opinion (which is why I got that 35mm f2 myself (on 1.6x crop factor APS-C))..
