So I just got a second Kerria today. I just finished blooming my first and she's almost as good as my Alpinia. I know FKG won't let you use the same char on a team twice, but would it be good to bloom my second copy and use her on team 2? Or should I try and get lucky with an upgrade so I don't have to use a Rainbow Dressbloom/Skillbloom to boost her?

This is a really hard decision so I wanted to ask before choosing on my own. Anyone with experience in this area?
