Change IDS to ⿰糹𦁀.

It's better to keep the current IDS because of the rationale, which the semantic element is 絲 and the phonetic element is 貝.

If the we use ⿰糹𦁀 as the IDS, it will make the people think the semantic element is 糹(糸), the phonetic element is 𦁀, and the shape of the middle element should be near to 糹 not current 糸.
