Funny idea, but not one I think really should be continued.
However, I do have some thoughts.  

Despite her complaints, Linna is actually better built than Akane.
She just seems to live in a country where people have inflated 
expectations.  I considered changing how I put that then figured,
why bother?  

On the whole there is no need for the character matches to be matched in
age.  I could easily see 19 year-old Kasumi cooking with 16-year-old
Makoto and 12 year old Sasami.  Also, I'm not sure what Makoto you are 
talking about, but if it's Sailor Jupiter, then her responses would be
a fair bit different from Kasumi's even if she loves to cook and clean. 
 
Marrying off one of his daughters will hardly solve Soun's problems.  
He's gonna need more engagements, and fast.
