You could just card it (don't have to be picture perfect rolags) into clouds and spin it like you would yak or buffalo or camel down. Those are all short fibres and are best spun long draw or woolen from a cloud. You could blend it with the silk or other fibres but silk is a much longer staple than what you have. I just got done spinning some suffolk fleece that was VERY short and I made tight little rolags with my hand cards (they resembled punis) and just did it that way. No blending.
If you are trying to stay in the same neighborhood staplewise then go with the camel.
