Would you want to see BloodClan in the series again?

Yes.

I like the idea of this more then I thought I would

That depends on how it would be handled.

I would not want for BloodClan to suddenly show up in modern times at the lake as villains but also do not think giving them more content where they terrorize the Clans during the past taking place in the forest territories is such a good idea either considering that it could kind of seem to deafeat the purpose of having Firestar save the Clans from BloodClan in the long run. Him and ThunderClan already had to fight them again in Ravenpaw's Path while Graystripe had to fight them off timeline-wise before that during the time Firestar and Sandstorm were on their SkyClan mission in FQ and GV. Keeping on to publish even more Super Edition or novella material set in the past where ThunderClan (or any other main series Clan) has to fight off these originally first series bad guys might get old and tiring plot-wise really fast.

So yeah, I'm kind of digging ᏞᎪᎠᎽ Ꮎf fᎪᏁᎠᎾms ミ☆'s idea of letting WarriorClan interact with them instead.

I think not. It was nice to see them again in Graystripe’s Vow flashbacks, but I think any more appearances would feel a bit to fan service-y, or like the writers are running out of antagonist ideas.

We’ve already seen them in GV, Ravenpaw’s Path, TPB, and TROS. And I think bringing them back with modern WarriorClan would kind of negate the idea that the Twolegplace cats finally knew some peace after Scourge/Fury’s deaths.
