The reason the Twins don't do this is because they actually want to win this year. Having a rotation of Santana, Berrios, Gibson, Gonsalves and Romero is a disaster waiting to happen. You don't put two rookies in the rotation to start a season when you have a legit chance, at least on paper, to make a run in the playoffs. Especially when those two rookies have a combined grand total of 5 starts at AAA. Also, as the Romero article that was just posted mentioned he's going to be on an innings limit this season of ~ 140. It's much easier to manage those innings in the minor leagues than it is in the MLB. There is ZERO reason to not spend money on one of the FA pitchers this offseason as long as the contract they hand out isn't 6 or 7 years. The Twins have plenty of money to spend before they hit their internal salary cap and barely have any players signed past this season.
