I would like to keep the weight down on the stand for easier transportation.

This gong stand is unlikely to need to be portable

Anyway the OP hasn't been seen for over 3 years, this is a zombie thread unfortunately reawakened by irrelevant spam.

A well justified query but I am making some assumptions. The spec was 'transportable' and not 'portable'. The 'design sketch' implies a much stronger frame than would be portable anyway. Just how big would the gong be if it needs 120 cm width of stand? Several kg of gong if it's that sort of diameter and it would be swinging (6m of alloy tube at 1.6kg per metre, plus clamps and a Tam-Tam can be 30kg). A commercial Tam-Tam stand. This is more than a classic boarding house dinner gong, of course.

The op design has only right angled joints in it, which implies sheer brute strength of the bottom support brackets. We'd be talking six metres of scaffold pole. A few 60 degree angles in the design and some braces could reduce the frame's mass by a lot.

We'll never know the outcome of this.
