Bad idea. More likely they attempt to move Springer to CF than trade him.. don't forget, they already have spent tons on Reddick, McCann, Morton, etc... and they still have gaping holes in CF, bench and the bullpen.
Plus, those young players are about to get expensive--Altuve hits free agency in 2019, and will likely demand a new contract NOW than waiting until 2019 after his options are exercised.. he is woefully underpaid, and will likely demand a trade if Houston doesn't give him a raise after next season. He should be one of the top-paid players in the game.. and Springer's arb eligible this offseason, and could easily get an 8-figure deal when he hits 2nd year arb.. and no way they're trading Gurriel or Bregman.
