The 24 f/1.4 is an amazing lens, but its main function is for shooting f/1.4-f/2.8. Now, while I grab my asbestos underwear, let me clarify that I'm not saying the 24/1.4 isn't good stopped down, just that there are several oustanding options at 24/2.8 which are cheaper, so if you don't need f/1.4 I'd suggest e.g. 24-70 f/2.8, 14-24 f/2.8, 24 f/2.8 etc.
...or if manual focus is ok don't mess around and just get the Zeiss Distagon T* 21mm f/2.8 ZF.2 which is probably the single best wide-angle lens available for Nikon F-mount.
Actually, your current kit is excellent and I believe will be fine. I think a bigger adjustment will be FOV change from DX to FX, all these lenses are going to shift their purpose.
