Falling back to 6 obviously makes it harder but I don't think it's a dealbreaker. Ive fiddled a bit on trade machine and came up with...
Boston trades: Jeff Green, Brandon Bass (expiring), Jared Sullinger, Joel Anthony (expiring)
2014 Boston 6th pick, 2014 Boston 17th pick, 2015 Boston 1st round pick,
Minnesota trades: Kevin Love, Chase Budinger.
Boston would get an immediate top 10 NBA player to pair with Rondo, would cash in half of it's assets, and have 2/3 of it's next big 3.
Timberwolves would get a huge haul of assets and a promising young player in Sullinger. Bass and Anthony are both expiring so they will free up some money in 2015. Minnesota also rids themselves of a bad contract in Budinger.

I honestly think this is fair for both sides. Boston might be heckled to give up an extra nets pick but I think they should fight it to use in another trade down the line. To the people I know will say Boston is giving too much up remember that you are trading for a 25 year old all-star entering the prime of his career. Boston will still have money to sign people this offseason and immediately compete.
