I could use a little help designing this...

Ok, I am not the worst at circuit design, but I am definitely not the best [noparse]:)[/noparse] That said, would anyone be willing to help me with laying this out, I was inspired for the idea by the below linked site, it allows for galvanic isolation of the 1 wire bus at the same time giving us the opportunity to do voltage translation from 3.3v to 5v. I would on top of the isolation of master to slave I would like to use this design to be able to deliver slave to slave isolation by bringing the master signal to 8 to 16 isolation points that will transmit to the slaves.
The site I got the idea from, all credit for this circuit goes to : Rudolph

So the highlights of what I am trying to do:
Isolation of master to slave and slave to slave providing a 1 to 8 or 1 to 16 distribution
Voltage translation of 3.3v to 5v
Longer lengths of a link in total by providing separation of slaves
EDIT: I forgot to mention that the slaves will/would be using parasitic power
