Create a board view from "My Approvals"

I would like to create a board view from "My Approvals" that supports:
•    Related entity selection so a user can have a different board view for RCIs compared to another type of approval (e.g Timesheet, Project Gate Approvals etc)
•    Related entity fields so a user can display the important fields from the related entity on the card (e.g Total Cost Estimate from the RCI entity) 
•    Related entity linked documents so a user can navigate from the board view to the linked documents on the related item (e.g RCI Linked Documents)
•    Drag & drop (only to approved & declined)
