I'm gonna go with some outside the box ideas. I like a good battle scene just as much as the next guy but sometimes your figures need to unwind a bit so how about these?

"Downtime" - shots of [insert faction] during downtime at their base/camp/etc.

"Homecoming" - showcase the return of a longforgotten member of YOUR collection, that figure you have but rarely use, returning to [insert faction] HQ... some are welcomed, some not so much.

"Road Trip!" - your favorite figs and vehicles on the open road.

"Family Vacation" - whether its the Clan Destro chillin' on a yacht in the south of France or a Joe subteam on a beach in Maui, showcase a group on holiday.

That's all I got for now. I'm sure I'll have some more "mainstream" ideas in the future but these are the fun ones I wanted to get out there now.
