Looking at your pics...I would say NO WAY would a land plane work as well as a rear blade...BUT I have never pulled a land plane...because my road is till/river rock base (very similar to your pics)...and it is extremely frustrating to have a larger rock lift an implement (rear scrape, box blade, rake etc., etc...) up and drop its payload untold times during each pass...
IMO unless you want to add *several* inches of uniformly sized gravel over top of the till...there will always be an issue with larger rocks interrupting the smoothing process...
