Same answer. Not trying to dodge your question or anything, but there is no one value chart, as much as fans like to refer to those out there.
Off the cuff/in a vacuum, it feels like 2 5s, a 6 and a 7 should probably be worth a mid-rd 4, yes. But again, it takes another team to WANT to do that deal with you, so practically speaking, it all depends on how other teams view the board, their draft, roster, etc.
