I'm not trying to be in the realm of historical fiction, or alternate history speculation. I'm not asking what if's about what if the plan had succeeded, but rather I'm trying to understand if there's any evidence within the known political climate of that time if the plan was arguable a good idea. Were the conspirators insane terrorists, or was their conclusion to bomb the parliament building a reasonable one? Could the damage of the building have prevented or delayed something? Were politicians back then more easily swayed by assassination attempts? Was the government so unstable that a big enough disruption could have caused it to collapse?

Something about the fact that people nearly 500 years later are still celebrating the failure of their attempt seems to suggests that it would have been very significant if the conspirators had succeeded, but i have no reference for what that significance potentially could have been.
