Collecting 4th and 5th rd picks won't get you far, you might package them for a 3rd.
Collecting 1st and 2nd rd picks allows you to trade for prospects and players.
Farabee, a 2025 1st and 2026 2nd could land you a young top 6 center.
We'll see if Briere can pull it off, if he can pick up a 1st and 2nd for Risto and Laughton, added to what they already have, that's enough to both draft 2-3 starters and pull off a couple trades.
It's a viable strategy, like any other strategy, you have to implement it well.
