Trading fantasy football picks?

My friends and I have a 10 man PPR league, no keepers, no flex, 2 wrs and 2 rbs. I'm thinking of trading my 1st, 5th and 7th round picks for my friend's 2nd, 3rd and 4th. I may also trade a 2nd and a 6th for another friend's 3th and 4th, but not sure yet. I would get 3rbs, 2wrs, Qb and a te with the picks. Think its a good idea?
