But what u r suggesting is to fill one hole by creating a gaping hole at the most important position.
First, before I forget, thank you for a constructive post.
Proceeding, let's set aside whether or not C is "the most important position", which, btw, IMO is influenced by perspective; i.e., C is more important now than generically whenever because atm there is a shortage of high end Cs, and the low supply with steady/increased demand drives up value/price. That said, The otherwise all around good team without G is handicapped, and likewise for without D, without Cs (esp. as to distribution/FOs), and without snipers/finishers (typically Ws). Rare is a team so complete it has no issues anywhere.
Now, while there is an obvious pronounced shortage of both elite players and better Cs generally, there is less visible a quality gap for players generically. If there were only still original 6 teams, the best guys would push off the others and every team would be great. Conversely, if there were 100 teams, it is logical to think that typically, quality would be dispersed further, with fewer teams having better players. (Similar to baseball after expansion, takes a bit for equilibrium to catch up.)
Ok, so now go back to a core point I made.
We only trade Stepan IF there is so much overpayment. By that I mean if we get enough (so much, actually, by definition), we are taking the plus we have at C and using that return to more than crazy improve the other areas.
That level of improvement, while yes, weakening the team at C, MORE than improves so much of the team elsewhere, the deal should be done on its merits. By definition ("MORE than improves so much of the team").
Restated, despite the big loss at C, total improvement commands acceptance of the deal.

Let's put a face on this.
Stepan does not get you JVR.
Stepan with reasonable + does.
JVR does nothing for you at C.
But JVR does a HUGE amount for you ---
on total offense, finishing, making other Fs, esp. Ws that much more effective.
So even if you live with the risk that Brassard will again step up like he did when Stepan was injured --- and it is fair to point out it is a risk, not that Brass will produce but if he will produce THAT much --- that risk is more than offset by actual JVR production.
That is what people have to get. It's less my opinion than it is mostly arithmetic.
The other thing, as I've said, is try to get most synergy in lines.
Kreider is our best LW. Arguably MSL = our best RW.
That is speed. So deal Stepan for top top top dollar, then add other currency and spend a few bucks to get Marcus Johansson from Caps (since guy we really want, Duchene is a pipe dream).
That's assuming MarJo is dramatically faster than JT Miller, who is a nice combo size/speed.
If we sign Hayes and he is ready sooner than later, that is a big line with Kreider.
maybe put Hagelin with MSL, for super speed.
We have to start thinking outside the box and not say 'oh, let's just tinker with one or two guys'.
IMPROVEMENT IS IMPROVEMENT.
