I think that this wouldn't be a problem in flight (assuming that you put the same weight on both blades

) but the prblem comes when the rotors stop!!
The blades would have to be much stronger to maintain structural integrity when static, this increase in blade weight would need a new head redesign, and would then require a bigger engine with more HP to recover Rrpm when pitch applied, this would then require a stronger engine frame to support the extra engine output, etc etc.
why not build a new helicopter and call it somthing like R44.
