BQ25710: USB-C Battery Powered Hub

Part Number: BQ25710
Other Parts Discussed in Thread: TPS65988, , BQ4050, TIDA-01243, TPS65994, TPS65994AD, TPS65988EVM

Hello, I am looking for help with device selection. Essentially what I am trying to create is a USB-C PD Hub (2 Ports) that has two batteries connected to it. The batteries run independent of each other at separate times so they are hot swap-able. I am currently using two 3 cell Lithium packs with the BQ4050 for a gas gauge. I have two BQ25710 battery chargers and a TPS65988 Dual Port USB-C. I need to be able to charge the batteries from the USB-C ports or power the ports from the battery and pass the data or video through to a controller. I have been looking at the USB-C Power Delivery Mini Dock (TIDA-01243) reference design. The controller will have one USB-C PD port to take power and information from my power module. I am wondering if the Mini Dock is the best reference or there is a better way to navigate this design. Thank you
