The easiest way is to setup a cron script which will do that for you. The script should move the first person (or first few people) from the waitlist to a pending state and send them emails with a page that they can go to and finish the registration (by paying for the event).

I'm pretty sure the cron sends them an e-mail with a URL to go to - the URL picks up from the started registration & allows payment

Hello marvs,

ParticipantProcessor.php first check the available seats for given event and then move participant from waiting list to pending state and send auto generated mail to primary participant for payment/confirmation.

Lets consider :
I do have event w/ waiting list configured, when event is get full and new registration comes in picture, it'd become a part of waiting list.
Now if by chance some confirmed registrations get cancelled or admin increases size/limit of event seats, subsequent cron ( ParticipantProcessor.php ) run check for first waiting list registration, validates for required seats and availability and then send auto generated mail to primary participant to confirm registration.

here for transfer of participant state from waiting list to pending, we do follow first come first serve basis.

hope it help
