No, not like that. Technically that only required a supermajority of miners to install the fixed version (and everyone to stop trading temporarily, but there wasn't much of that going on back then anyway). This would be harder because it really would require everyone to upgrade. BIP50 is probably closer; that did require everyone to upgrade over a relatively short timespan or work around the issue by changing a setting, ironically enough due to a latent bug triggered by increasing block size closer to the maximum 1MB.
