Install Lineage on P3110 with Replicant
I am thinking that I may have to install espresso-common_TWRP_3.2.2-0.img but I have found no way to do that from the Replicant bootloader.


I think you are correct, I don't think you can flash a new bootloader with the Replicant bootloader, only update it. 

You will have to flash with a computer:


Plug your device into a computer
Put your device into downloading mode
Flash TWRP for your device


And then use TWRP to flash the LineageOS ROM for your device.
