short answer: yes, we can work something like this out for sure
longer answer: my original intention was that the direct family positions for these characters would be open for PCs to fill (i'm also willing to futz their biographical information if anyone would like to do this but already has a character concept/name in mind), so this will be partially dependent on if anyone is interested in filling these roles with PCs.
if you'd be open extending this concept to other members of the flume/keaton family like siblings/hank's children/etc i'm sure we can work this or a similar dynamic for john out, though! i doubt every member of both family is going to end up as a PC (although i would be deeply delighted if someone wants to play a 60 year old ranch wife lady tbh)
