Need advice for NEX setup coming from P&S

so I have had a panasonic LX3 for the past 4 years, I took beautiful pictures with it, however I want to update to something with better IQ, video, and better OOC colors.

I do a lot of outdoors, landscape, nature pictures and some wildlife. I mainly do small prints and watch pics on TV/monitor.

I am willing to accept more weight/volume as a tradeoff but I am not sure if a 5n/5r would be the best choice for me.

The LX3 has a 24-60mm lens, I analyzed all my pictures with exposure plot and noticed that I mostly use the 24mm or the 60mm (this is probably because I want a longer tele), so all the prime lenses in between wouldn't serve my purpose. At this point I could either use a w/a legacy lens and a tele lens or the kit zoom lens. Since I prefer portability than the kit zoom might a better option. Also I like macros but I probably will have to crop with the NEX.

What do you guys suggest? I was thinking of getting a 5n body only and then the 16-50 but its expensive. Does the 5R have the same IQ as the 5N? I even thought about the nikon V1 as an alternative but I would have less IQ for cropping. Is a NEX unexploited without the use of legacy lenses?
