I wonder if it even makes sense for this manga to become a drama. I think the majority of gag action mangas just transform to action dramas anyway. This manga, however, satires that.
I think epic 2 page spreads per frame of action is as dramatic as the manga gets. I can easily imagine each frame (while taking nanoseconds of real time), is actually just Saitama's POV, and seems like 10 seconds per frame.
