Thoughts about comic events?

Hello patrons! I've been working on the first few pages of what I hope will turn into a successful comic-style event, but because of the format being different from BOC, I've been hitting a few snags on how it would work. I know that I want it to run in the same way, with patrons/donators determining which subject(s) will be stuffed in each particular update or chapter, but I'm just not sure how to go about it, since the storytelling-type format will require a LOT more art to be done in correspondence to each determining donation. (I had originally planned not to even attempt an ongoing/comic-style event until I reached the $1000 stretch goal, but I'm excited about this and really want to try to do it with you guys!)

My thoughts so far have been:

• Comic page updates will be visible to Patreon users 1-2 weeks before being published on dA, and will be available in high-res to patrons of $10 and above. I am considering adding a $3 patron tier for people who just want to view the pages early but receive no other benefits, though all other art will only be available to patrons of $5/month and above. I figure adding this may help to boost stretch goal amounts towards higher goals to unlock better rewards for all patrons.
  
• At $500/month stretch goal achieved, I will do one full colour page (3-6 panels) every month, but only patrons or donations of $50 and above will determine who gets stuffed in each update (with food/etc. doled out in $10 intervals to be determined by the patron/contributor, just like with BOC). Chapters will be relatively short but stuffing results will be immediately visible once each page is published (though weight gain results will have to wait until the chapter concludes and the following chapter begins). NOTE: As this is going to be a story-format event with a larger plot than BOC, I cannot promise that every update will include some sort of stuffing, as some updates will be necessary to advance the plot outside of the stuffing component of the comic, but I will try to keep non-stuffing/wg updates to a minimum unless absolutely necessary.
  
• At $1000/month stretch goal achieved, I will do one full colour page (3-6 panels) every month, but only patrons or donations of $20 or above will determine who gets stuffed in each update (with food/etc. doled out in $10 intervals to be determined by the patron/contributor, just like with BOC). Chapters will be longer and will take more time to conclude, but they will also include more characters getting stuffed, and stuffed bigger, as well as more noticeable weight gain on the start of the next chapter.
  
• The higher the stretch goal achieved, the more pages I would be able to do for each monthly update, but as always it's best not to count chickens before they hatch. As it is, I MAY be able to do another page or so some months depending on if I have time, health, and energy, but I will never do less than the promised monthly amount unless something comes up, in which case I will do my best to make it up the following month.

Thoughts? Feel free to let me know if you have a different idea you think might work better than this - I'm still brainstorming while I work to put everything together!
