AFAICT that doesn't look possible. When I tried it in devstack I got the 
following result:

$ openstack server migration show testVM 5 --os-compute-api-version 2.24
Migration 5 for server f1aece4e-e7f7-436b-9faf-799129503dcc is not 
live-migration. (HTTP 404) (Request-ID: 
req-84e97eaf-d3b5-4287-8a52-b5193b038447)
stack at ubuntu-controller:~$

And this is the code that blocks other migration types when showing a 
server migration by ID:

https://github.com/openstack/nova/blob/eaca6b7e664b1980927c0595e5a792d8bbab8b92/nova/api/openstack/compute/server_migrations.py#L135

That said, if it is somehow allowing showing any other migration type 
than live-migration, it is a bug.
