To convert 2nd row from 2 captain seats to full bench.

Hi Freeders,
 
I just joined this forum. I don't have a Freed instead I have a Vios. I'm very keen to buy a 2nd hand freed. I wish to have a freed with dual powered sliding doors for convenience, cvt for fuel economy and 2nd row full bench because my daughter like to sit with my wife sometimes.
 
From what I have gathered so far, only the freeds from Kah Motors have dual powered sliding doors but they do not have 2nd row full bench and is 5 speed auto.
Only PI freeds have 2nd row full bench and cvt but only left powered sliding door.
 
Seems like the only way around it is to get a Kah Motor freed, and convert the 2nd row to full bench somehow and live with 5 speed.
Does anyone here had this done?
Or do anyone know where it can be done and how much it cost?
Or have people in this forum actually swap 2nd row with each other?  
Or anyone interested to change from full bench to 2 captain seats then I can swap with you after I buy my 2nd hand freed?

Or can I get a left powered sliding door and convert it to dual powered sliding doors?
 
FYI, there are only 2 Kah Motors freeds and there are only 2 PI freeds with 2nd row full bench on SGCRMART.
