1 - it is. 2 - how likely do you really think a freewheel is to skip? And when they do skip, are you aware that they simply move onto the next EP, meaning you get reduced power, not no power, so in many cases you don't end up on your teeth? 4 - whatever, not really clever 5 - you're on about buying a whole LHD system, complete with ACS, when the money spent could buy a freewheel that won't skip, unlike an ACS? 6 - if they're actually LHD cranks, then the pedal thread's going to be in the right way, isn't it? 7 - you say normal cranks have the room for this on the non-driveside. So where exactly are you planning on putting the freewheel? There's no thread there.
