Portland wouldn't give up Nurkic...no way..no how.
The best we could hope for from a wing perspective would be a combo of Harkless/Aminu but I don't think Portland would add Aminu because that leaves them without a starting caliber SF to deal with guys like KD/K-Thompson.
The best player/player deal I would prefer would be Melo for Harkless/Aminu/Vonlay/Napier but I don't think Portland parts with Aminu...leaving them with no D at SF.
If we assume Harkless/Vonlay/Napier...the Blazers could add in E-Davis and the deal works and it leaves us with +$13M in expiring deals next summer (Vonlay/Napier/Davis)... so no long term damage. Harkless is 24, Vonlay 21, Napier 26 and Davis 28.
If we could get the Aminu deal would love that package.
