No, the solicited node multicast address is not tied to the MAC address. For every IPv6 unicast and anycast address assigned to an interface there will be a solicited node multicast address with the least-significant 24 bits of the IPv6 Unicast/anycast address embedded in it. The solicited node multicast address is also used for duplicate IP address detection. If you would use the all-nodes multicast address it would behave like a broadcast and you would get a reply from every node on the link.
