Why just copy the original pool? It won't get off the ground that way, there is already an original...

So: find a target group (people with fast home PCs), then set your pool to benefit those miners.  
Small winner %, medium current %, large historic %, so  5%/25%/70% or similar. Make the historic period sorta short (PCs running only a few h/day).
Then encourage people to show up: Fire up some instances at google or where ever you get the most bang for your buck and win some ARO.
Or have a negative fee (0.25%) for a while, i.e. you pay them to show up and mine at your pool.

EDIT: also do a new Design

GOOD LUCK!
