Some very rough number-crunching, done using the Forbes' estimates of NHL team revenues in 03-04 and some probably-unjustifiable interpretations of the contradictions and vagueness in the G&M article:
I calculated the floor figures as being 35% of revenues, based on the floor 24/cap 36 number quoted in the article - if a 36 cap was 54% of revenues, that's about $67 million in revenues, and $24 million would be 35% of that. The cap is calculated as 54% of revenues.
The 'new cap' is based on the assumption that any luxury tax paid would apply towards the overall cap, so the effective cap would be halfway between a team's 54% cap level and the luxury tax level - i.e., for the Rangers, it'd be $52.3 million, because the luxury tax level would be 40.8 million, halfway between the top cap (Rangers) of 63.7 million and the lowest floor (Sabres) of 17.9 million.

(all numbers in millions)
Assuming everybody spent to their cap, $64.2 million in luxury tax would be paid by the ten teams that went over the soft cap level of 40.8. No idea how that would be split up, but even in the worst case for the lowest-end teams (an equal split of it between the 20 under-soft-cap teams), it'd mean an additional $3.2 million in cap room. So in the end, there'd be a high cap of $52.3 million and a low of $30.7 million, a 70% advantage for the bigger team. In 03-04, according to the numbers Forbes used, the high-low was 80-29, a 176% advantage.
So (if I've interpreted things 100% correctly, which I doubt), that would seem to make the smaller market teams a good bit more competitive, but whether or not they'd be "competitive enough" is far from clear.
