So, the coming timetables for the trains from Finland to Haaparanta in Sweden have been published now. On working days two trains per day and direction. On Saturdays ("la") three, on Sundays ("su") three as well. Ol=Oulu, Hpa=Haaparanta.

Leaving 5:08 in the morning from Oulu is humoristic! But expected, as VR wants to prove passengers don't want to use this connection.

In practical terms there's one usable train per week: On Saturday.
(All times are in EET)

This does actually seem to produce a somewhat usable interchange connection from a Helsinki–Rovaniemi night train. There is a 16-minute interchange in Oulu, and probably a few minutes less in Kemi, where the night train stops at 5:58. It's not super fun to have to wake up before 5:58, but it's a thing that can be done.

That gets you to Stockholm by 20:38, Mon–Sat.
