Potential children for Luna! Where was Hasbro going with this?

[ManaMinori 4,145]

For those of you who don’t know, Hasbro created these two ponies- one named Star Dreams, who had been released on 3 separate occasions- the first being in a slumber party set with Applejack, the second in a set with the CMC and their classmates (silver Spoon, Diamond Tiara, and Twist), and her third release being in a spa set with Rarity and Rainbow Dash. 
 

The second pony goes by the name Lulluby Moon, and she was released only once, as as “so soft” brushable/plush pony, along with twi other ponies sold separately in the same line, Apple Sprout and Sweetie Belle.

For the longest time, I have wondered about and fawned (created theories, headcanons , art, and fanfics) over these two adorable little ponies (Star Dreams primarily), though have often entertained the idea that she and Lullaby Moon are (headcanon) or might have been (if given the opportunity to be written into comic or show canon) sisters, due to their similar names that would allude to being born of Luna.
 

Given her affinity to children throughout the series, as seen through her being especially close to the CMC in some episodes, it wouldn’t really be that far fetched, to assume that the writers might have played with the idea of Luna having daughters at some point, but just decided to have her be more of a close mentor for the CMC instead, due to possibly potential avoidance of fandom backlash or already established characters within the show. 
 

But I’m interested in you guys opinions. How could Hasbro have incorporated Star Dreams and Lullaby Moon into the show or comics? Do you feel like the three releases of Star Dreams’ toy was building her up for some involvement in the show? Will we see these characters in g5? Share your thoughts!
