Hello Alex
NX-OS has a nifty feature that lets you resolve issues like this. You can actually resequence the numbering of an ACL using the following command:
resequence {ip | ipv6} access-list <name> <starting-sequence-number> <increment>
You can find details about this command at the following NX-OS command reference.
Take a look and let us know if you have any other questions.
I hope this has been helpful!
