Would a mirrorless Nikon camera be a good choice for a strictly landscape photography?

I have been doing research lately to find a good lens for landscape-milky way photography so the aperture need to be quite open to minimize star trails (keeping the shutter speed in less times). It also needs to be quite a wide lens to capture all of the milky way. I found a perfect lens for this, it's the Nikkor 1 10mm f/2.8 lens. It's only for the mirrorless camera. I don't own a DSLR or a mirrorless camera. I've used a DSLR in the past but I no longer have one. Would it be a good idea to pick up a mirrorless Nikon 1 camera? If so, which do you recommend as I can afford pretty much any Nikon 1 mirrorless cameras.

I've been concerned with one thing, that is the small sensor size on the mirrorless camera. Compared to a DSLR, the sensor is quite small. I'm not knowledgeable on sensors but I've heard bigger sensors = better light gathering abilities. Of course, I'll be doing milky way landscape photography so this is important for half the time as I'll be shooting in the dark. The other times, I'll be doing sunrise/sunset landscape photography. Megapixels don't matter much unless you want to make billboard sized print which I won't be doing.

There are only two lenses for Nikon mirrorless cameras which allow you to shoot landscapes:

- Nikon 1 Nikkor 10mm F/2.8 for about 250 USD
- Nikon 1 Nikkor 6.7-13mm F/3.5-5.6 VR for about 500 USD

As for the Nikon mirrorless cameras, the dynamic range of the sensors of those cameras is not high enough to get the impressive landscape shots.
