mark your own by chopping up an alu bodied SRAM or some such like. Could be fun!

carefully cut the cassette up into individual rings and then use 7spd spacers between. There are some super rare Mavic cassettes too if you can find one.

Real was the cassette I was thinking of - lower cogs are all seperate.

I made a light 7 speed one once. You need two xtr cassettes (m900), a q type and a p? type if I remember correctly. One has more rings on the spider than the other and you simply need to use the loose rings from one on the other to maintain decent ratios and end up with a 7 speed cassette on a lightweight spider. Simples.

I think it's the m900 spider that riveted and you can grind/Dremel them off without ruining the cassette and then mix and match cogs?
Although using a compact cassette in general is going to be inherently lighter by a fraction due to the smaller cogs.
