Yes that's fine.
Just check that an off peak return doesn't meet your requirements and that the ticket you choose is valid on the route you travel on
There isn't an "Off Peak Return" via Burnley, which is the route the direct trains take.
This is because the Saver Return, along with all other non-London area Saver Returns, was always traditionally valid at any time. This fare therefore correctly and commendably became 'Anytime Return' at simplification.
It's a shock to see a Train Company
not using simplification and/or privatisation as an excuse to erode the flexibility of the protected fares, but it really is true (I know it's hard to believe) that Northern (and their predecessors) have kept the old Saver fare's validity intact
and gave it the most appropriate name possible post-Simplification.
Most other Companies have simply screwed their customers.
