What would be the best way to combine an LTC3109 and ADP5092 on the same PCB?

Hi everyone.

My name is Leandro, I work as a programmer in Brazil and I'm learning electronics in my spare time.

As a derived prototype project from another one I'm working on, I want to use a small Peltier plate together with a small solar cell, so the combined harvested power could power up a low power circuit and charge a battery with the surplus.

I'm thinking about using the following ICs:
https://www.analog.com/en/products/ltc3109.html - For the peltier plate
https://www.analog.com/en/products/adp5092.html - For the solar cell

However, since both ICs can charge a battery, how can I "link" the two? Can both ICs be connected to the same battery at the same time?

Also, about the VOUT / REGOUT of the ICs, assuming the same voltage, can both be connected to the load at the same time?

Any help or alternative solutions would be appreciated.

Thanks and regards.
