Trying out new build on LB: ROA-> Hextech

OK, so I made a thread about hextech being bad on LB, and I admit I made that thread just to see people's reactions. I ahve been playign with hextech on LB and I think it's pretty good.

However I though that LB can use some extra HP for more survivability throuhgout the game, so with 20% scaling CDR runes, I tried :

RoA-> Hextech-> Void staff-> Lich bane(can switch orde)-> Ionian-> Rabadon Roa-> Hextech-> Lichbane-> abyssal-> Rabadon-> Voidstaff(no shoes build)

I wonder if people can try this build and tell me how it is. So far it worked for me pretty well.
