Endurance event idea

I was thinking today that I would probably watch an endurance event in snooker, especially because it would be an interesting alternative to the currently existing events, kind-of like Le Mans is for motor racing.

Here's my idea:

Event name: The 47

Event place/venue: Whatever

Setup: Multiple qualifiers leading to few endurance matches (e.g. actual event starting with 16 players); Qualifiewrs would be longer than for normal events, but still single-session

Win condition: First to 47 frames wins the match (best out of 93)

Organizing: Per match, maximum 10 sessions (9 x 9 frames + 1 x 12 frames). This is the theoretical maximum, but usually there would probably be fewer sessions. Organizing needs to be more fluid than on current events, being impossible to really know in advance when certain matches would take place and how long would the whole tournament last.

Special rules: 1. Premature win if you lead by more than 10 frames in a match at any one point; 2. Maximum break has a bonus of 2 extra frames won (e.g. you win 3 frames at once)

What do you think? Any other ideas?
