Looks good, what do you use to edit; and what's your capacity? Because that's the only thing to really consider, is that your file size will be so much bigger than 1080p files.

Other than that; go for it!

PS. Actually just thinking about it; so few people have the screens to appreciate 4K, however the 1 inch sensor will give you better looking 1080 than a gopro so you can still keep file size down and get a better output.
