MiNA's inclusion just gave me an idea for what a Trickster's blighted skin could potentially be.

Similar to how Blighted Legion is Frank having Julie, Susie and Joey fused into his body, blighted Trickster should be similar in concept. Basically have both Trickster's body and MiNA's body fused into each other, to create a beautifully grostesque and scary fusion between the two, along with alot of orange pustula nectar coming from them as well.
