@ LarryC,

Actually the rotor mass makes no practical difference just so long as it is balanced.  It is nothing but a flywheel.  It will slow acceleration and deceleration times but not affect whether a torque force can rotate the wheel (assuming no increase in friction).  It actually smooths out the cogging effect that is slowing the wheel each time you approach the walls.  A lighter wheel would spin down faster if started at the same RPM since it has less inertia.

This way the repulsive force could be reduced because the repel magnets would not approach each other perpendicularly but the "stator" magnet would just come anticlockwise from below and could push upwards the rotor magnet in the switch gradually.
...What do you think?

Always good to hear new ideas - but,

Friction is already a problem.  The gears will add even more.  And then there is the extra energy needed to drive the gears/stator wheel.  Those 2 added up (or even one) would result in more "energy" loss than the magnetic wall IMO. 
If anything - use pulleys - as they can be upwards of + 94% effecient, are cheaper, and can be easily sourced.  But again - IMO - too many losses.

A variation of the idea would be to have the gears with just a couple of teeth, so that it only engages briefly so as to rotate the stator like 45 degrees, to like 12:30, with the stator magnet slightly angled, and then the stator drops back down due to gravity to like 3:00 and is supported by a rod/latch etc..

I'm not saying a lighter wheel. Move that wasted rotor mass out to the magnets and it increases the leverage to break the walls.

Glad to hear that you're still going to give it a real try. I have my doubts about the design, but would still like to see your results. Especially since TK's device was just a work of art engineered to fail. Nobody making a serious attempt, would try to move such a large rotor mass with those few little magnets and try to break two walls. I'm sure its value was to show that if such a well built device can't run then what's the use of  anyone else trying.

Larry, with all due respect, you don't know WTF you are talking about. The wheel in the video  is so well-balanced and the bearings are so free, that the imbalance caused by a SINGLE SLIDING MAGNET remaining out-of-position provides more than enough torque to rotate the wheel until the imbalance point is on the bottom. This can be seen in the video in certain places, as the wheel rocks back and forth around the repulsive "wall" at the end of several stator trials.
Build a better one, show it, THEN criticize my work. Otherwise, you can take a long walk off a short pier, because you are already all wet.

Hi Mondrasek and All,

I would propose an idea of placing both stator magnets onto two separate small wheels (planet? wheels) which are geared to the big rotor wheel at 12 and at 6 o'clock positions and the gear ratio ought to be chosen so that when one mass switch is just passing the stator magnet, by the time the next mass switch arrives the stator magnet already have made one full circle on the small wheel.
This way the repulsive force could be reduced because the repel magnets would not approach each other perpendicularly but the "stator" magnet would just come anticlockwise from below and could push upwards the rotor magnet in the switch gradually.  I attached a small drawing showing one small wheel with the stator magnet on it at 12 o'clock and the big rotor magnet switch at the 6 o'clock position.
What do you think?

Sounds good Gyula, maybe with some other mechanical integration it might work.
