Obviously, Ineos would have to evaluate the cost against the benefit, but if you ignore economics, taking Remco IMO is a no brainer. Those guys you mention are solid riders, but I disagree that they must think they can take on Vingo and Pog in the Tour. Of course Ineos transformations have happened, but the only one who should realistically be thinking about that is Bernal if he can fully recover and improve from his previous level. I would trade Remco for any 3 of the riders you mention personally. And I like those riders. Also, Bernal, TGH, G, etc have already shown an affinity for riding other GTs. Very easy to go with Remco and, say, TGH as 1a and 1b for the Tour, while having G and Bernal for the Giro and Rodriguez and Martinez lead the Vuelta for example. Arensman should continue to superdom like Bernal did and see if he can rise up further.
