Can inventorship be corrected through reissue instead of reexamination?

Yes, inventorship can be corrected through reissue if it’s not addressed during reexamination. As stated in MPEP 2250.02:

“Alternatively, the failure to name the correct inventive entity is an error in the patent which is correctable by reissue under 35 U.S.C. 251.”

The MPEP further directs readers to MPEP § 1412.04 for more information on when correction of inventorship by reissue is appropriate. This option provides an alternative method for correcting inventorship errors in patents.
