create a new organic group when group doesn't exist

I'd like to combine the 'autocomplete' widget with the 'inline entity form - multiple' widget to create a new groups if the groups don't exist.
My Though was to use autocomplete to find existing groups and to return the groups that don't exist yet into the inline entity form, so the user can create the new groups.
I'm thinking of using some jQuery to do this - but is there a simpler way?
