Peggle Deluxe has a NG+ category, so why not add the category to Nights, too? I just did a run:

The rules, copied from Peggle Deluxe NG+ rules and edited slightly:

"Beat Adventure Mode with all the Masters unlocked as quickly as possible.

Timing starts on starting a new adventure on the main menu and ends on hitting Continue after clearing Shadowshine."

I'm proposing a new category: All championships.

Rules: Play every championship in order from easy to hard: Birchwood -> Oak Park -> The First -> Spruce Copse -> One by One -> Scary Set -> Torment Fields. Timer starts when you hit "Start" with Birchwood selected and ends when you complete Torment Fields.

Here's my 30:03 run:
