I would be OK with it, but the graphics engine needs a serious overhaul (too stale/bland, maybe make it more in the vein of Super Mario Bros. 3 with Wario Land Shake type graphics). And the music needs a serious bump too.
But since the Wii casual "too dumb to play games of any actual complexity" is gone, I don't think there should be any real rush.
Mario Galaxy 3 or even Mario 3D World 2 would be more interesting I think. NSMBU + Luigi U + NSMB2 + Mario Maker are plenty for a while.
