Programming a propeller I with a raspberry pi pico

Is there a way to program a Propeller I microcontroller with a Raspberry Pi Pico instead of the more expensive Prop Plug? Since both devices operate at 3.3V, and the Pico should be capable of emulating the Propeller's communication protocol, it seems like this could be a valuable, less expensive alternative.

The Prop Plug is just a slightly modified USB to Serial converter. The non-standard part is a capacitor on one of the flow control lines that resets the propeller without holding it in a reset state. I did a quick search and found this https://github.com/Noltari/pico-uart-bridge/blob/master/uart-bridge.c but it doesn't handle the flow control lines.
The attached program uses a P1 to load another P1. It will help you understand the protocol.

Everyone, thank you for your help
@Don M - I will be trying your code tonight....thank you
Did it work?
I am interested in converting to Basic.
