Is it the right time to make that type of deal though. All of these guys should be more valuable a year from now, after another year of development and being closer to the majors. Orelvis for example should reach full season A ball in 2020, or even start there and elevate to A+ by the end of the season.
Also, a philosophy of sustained winning means you don't trade your high end prospects and in fact even when the team is a contender, you are still trying to acquire elite prospect types.
