BQ25504: Adding USB charging to BQ25504 solar energy harvesting

Part Number: BQ25504

Tool/software:

Hi, I'm designing a wireless sensor and it runs on a LiFePO4 battery and can be charged from USB using the MCP73123 as LiFePO4 charger delivering energy into VBAT

Now I'd like to add a Solar Cell as an optional energy source. It looks like the BQ25504 has all the features I need.

But can it be used in parallel with the MCP73123 ?

Here is a quick schematic of what I'd like to do

Thank you for your advice.
