Ok, let's clarify the discussion here a bit:
The key decision point for a re-tool is the likelihood it can be successful, even with Pettersson, Hughes and Demko in place. Given their cap, contracts, needs, timeline and assets... it's going to be very difficult.
For Tampa: I was a bit presumptive here. What I did was take your proclamation that 4 teams were able to re-tool quickly, and I had applied it to Tampa's history. Clearly, there was a much stronger base there than it is here.
For the Canucks: The first place to start is their 5 year record: They rank 24 of 32 teams with points accrued:

And so, no matter how close you feel they are versus how far I think they are, that has to be acknowledged first. Then, we evaluate Horvat out Hronek in, as well as the impact of normalized goaltending.
I will remind though, that being on the bubble in 2021-22 does not a consistent playoff performer make. We know the goal isn't to win a cup here, it's just to create a consistent playoff team. Therefore, I would consider a successful re-tool something that places us within the playoffs for 5+ years. Do you believe the odds are good that this happens given everything we know above?
