The values are reasonable, if you did any three to five of these. After that, GMs start noticing the scarcity of first round picks, and raising the price to acquire one. Division rivals especially start to fear your impending dynasty and won't even think about it. Plus, there are some teams each year that just won't trade their first round pick, and others who won't trade it unless there's something they specifically need, down the stretch, that they feel gives them a much bigger shot at a championship. So this is functionally impossible. Storied teams that burn everything to the ground for picks typically come away with three, maybe five first round picks. They may get value back that's worth much more than that, in terms of decent prospects and younger players.
As for whether it's a good idea? No. FIrst round picks are usually given lots of extra chances to succeed. A team with thirty-one of them and 23 spots can't give everybody sheltered minutes.
