One thing about this Pradhyumna track - while SB covers it in a single chapter, fact remains that after Pradhyumna disappeared, there was a major interval of something like 16 years or so b4 he returned. So showing the track this way doesn't look good.
What they could have done after they completed the Syamantaka gem episodes would have been show Rukmini pregnant and then give birth, and have Shambara kidnap Pradhyumna & disappear. After that, Rukmini could have quietly exited the scene, while they showed Narakasura. And brought back a Rukmini for the first Sudama track.
That way, they could have shown everything they showed in b/w, and now, switched over to Pradhyumna. That would have made a lot more sense than the saas bahu show they're putting on b/w Rukmini & Satyabhama.
