help with blueberry on the rocks cider!

[Brewing allsorts]

Im quite new to brewing up different drinks, I’m on my second cider the blueberry on the rocks kit, I’m going onto the next step can I skip using another fermentation barrel and place it in the pressure barrel or will I definitely need another fermenter ? Thanks

You'll simply end up with more sediment in your barrel I presume that's the only obstacle that should be any issue buddy
