Hi, Number 6 was proposed in https://www.unicode.org/L2/L2024/24232-compound-tone-diacritics.pdf as U+1AEC COMBINING CARON ACUTE and has been provisionally assigned ( https://www.unicode.org/L2/L2024/24221.htm#181-C34). The other numbers 7, 8, 9 seem like candidates for a proposal.
While the sequences of already encoded combining marks can look identical, they do not always do so and may in fact be in a confusing order, semantically they are different as well.
