I see what you mean but they already challenge the classics pretty well. There is also Van Wilder and BagioliI would be happy to take Cattaneo, Cavagna, Lampaert as my TDF doms. But there is a limit to how many of these workhorses you can utilize.
I don't understand why the merger isn't happening with Lotto. Those teams are much closer in spirit and they already swap sponsors all the time. Just keep the top 5 lotto riders and merge into the Wolfpack, and you might actually have enough firepower to challenge in the classics.
