over unity by 'Reaction helping action'

Very Good!

With your comment 2 of para 1 (pivot moving with plane) you are coming closer towards reality. The mass would go the other side of pivot only if you use short string and W3 is not well placed on the support and also if the plane moves far too downwards.

Now just forget about external support,  find out the exact gravitational center of the plane and place your support there.  Now if W3 is made to rest on the support(ie., support is raised like car jack to nullify W3),  entire plane would move along with pivot and support keeping all positions fixed and pivot remains perpendicular to the support at all positions of the plane.  In this case weight W3 will not move to the other side of pivot unless it is free to slide on the support.  You have to prevent both W3 and support from sliding. Keeping support at the center is not going to affect the lever effect since lever arm at the center is zero.   Don't allow the plane to go too far down.  Limit its movement to some extent. Keep in mind that the experiment is dependent on vertical component of gravity vector.

Any way thanks for applying your mind and sparing your time in conducting the experiment.

Thanks
