some assistance in storing/maintaining a value in AEM and replicate it to the publishers

TLDR: I need to store a value in AEM author. I need to be able to change the value and then published that value as well. I am thinking of saving the value somewhere in /conf/my-apps (example: /conf/my-apps/my-node)?

Thanks!

some info: (these are just some initial thoughts. feel free to make suggestions)

• The value of the field will be changed using an author-only page (need to use view-as-published)
• After submitting the form, a servlet will then...
  1. create /conf/my-apps/my-node in author if the node does not exist
  2. servlet will then create a new property in the node (example: my-value) if the property does not exist
  3. servlet will then save the form field value into the property
  4. lastly, the servlet will replicate (com.day.cq.replicator?) this node (example: /conf/my-apps/my-node)
• My AEM is using AEMaaCS.
