This is awesome. JIRA migrations are a massive headache, and the fact that you open-sourced a working solution is solid. OpenProject isn’t the prettiest, but it gets the job done, and cutting out Atlassian’s costs is a win.

Turning this into a paid service makes total sense—plenty of teams don’t have the time or patience to deal with migration. You could probably gauge demand by reaching out to OpenProject users directly or posting in places where people rant about JIRA (which is… a lot of places).
