I could make an argument I would take any of the guys I listed over Verlander for 2018 + 2019. I'm not saying its a slam dunk.
FWIW, I listed guys who are free agents, or could opt into FA. Those cost you 0 prospects. There are many other pitchers who would be "available" like Verlander, via trade. Most of those others aren't going to be 35 and making $28 million / year
And as I said, there is a big gap between your valuation of the players you listed and mine. The only two you mention that I'd rather have over the next 2 years are Arietta and Darvish, and both of them carry as many question marks as Verlander. The guys you mentioned as in his class, just aren't. They are worse now, in some cases they are as old or close to as old, and they don't have the track record Verlander has...you are selling raisins and calling them grapes. One could argue that Cueto and Tanaka fit that same mold as well.
Look, this is just wishful talk, but if there was a realistic chance to land Verlander without giving up a pile of prospects, it's probably the best way for the Twins to improve their staff for the immediate future. As much as I'd like to think the Twins could be in the running for Darvish or Arietta, I doubt that will be the case.
