Should Samsung make a sized ranging flagship set?

Remember what HTC tried to do with the One series? Should Samsung try to do something like that with some decent smaller phones and some larger phones?

When the GS4 comes out it could be a flagship range like this:

Galaxy Note 6.3" $700 All the latest specs, 13MP, Exynos 5 Octo, 2GB RAM, 1080p

Galaxy S 5" $550 Same specs as the Note

Galaxy S Mini 4.3" $400 Slightly lower specs but not bad. 720p, 8MP camera, Exynos 4 Quad, 1GB RAM
