Outside of the fact that it isn't realistic at all, Belt is a 4 win player on a super affordable deal. Lets assume he averages 3.5 WAR going forward. He's controlled through 2021. So that is 15.5 WAR x $10 million= 155 - $71 = $85 million in surplus.
You're gonna have to give up something like Adames + Snell/Honeywell/De Leon. That package would have about $82 million in surplus value which is just under what we need. So add in a lotto ticket and you have
Adames + Snell/Honeywell/De Leon + Jacob Faria
