To be honest, if I were you I won't try solo the boxes, hoping to get all the cards.
 * I once soloed 5 box of WX03 for building Umuru. It happens that all of that 5 box have only 1 Lost Technology and no lv.4 LRIG or SIGNI. I got only Red and White LRs and no ones want to buy it.

I suggest you either straight away buying a singles or finding someone who wants to share for the other color.
