The bolded is how I know you haven't really thought your timelines through on this. What year is this magical lineup supposed to ever actually play together? Soda will be expired before Cozens is ready for the NHL, much less being the 2c on a cup winner in the NHL. Or are you suggesting that we pay a 35 year old Soderberg to do the job that Kamenev & Bowers are being groomed for?
This fusion of present & future might look pretty if we imagine them all being at the height of their powers at the same time, but that's not the reality we're stuck with.
Even on our deep blueline there's potential for us to run into similar problems as well...as EJ is already looking shakier than ever before & Cole finishing his contract playing as well as he is right now is still far from guaranteed.
Although there the timelines mesh a lot better since Makar is already in his draft+2 year, so he should be able to hit the ground running a lot faster than any non-Hughes or Kakko forward and we need a lot less from him than we do from any forward we bring in to "solve" our 2nd line. Similarly, EJ & Cole's aging shouldn't be
that troubling with Barrie, Girard, Makar, Zadorov, Meloche & Timmins already in the organization either already filling or being groomed to become top 4 caliber guys.
PS I can't wait to see how many NHL games it will take folks to turn on Kaut like they have Jost...it's almost like setting unrealistic expectations for how quickly prospects will reach their potential, while banking on that potential to fill current holes, might not be the most sound approach to roster-construction or talent-development
