That might work. A quick mental calc says about 4mm deflection at 1m with 600mm of rod in a 600mm tube (ie min height would be 600mm). I need to do more accurate bending calcs and torsional calcs as may allow too much rotation Weight is about 2.9kg. Only downside is a 1" pole looks aesthetically 'flimsy' lol
