Raspberry Pi 4 model B?

Ok. This is probably a stupid question, but I was looking into mods in my flipper zero and I found the esp32 and the video game module are both really high. The video game module is just a pi pico and the esp32 is literally an arduino with WiFi and Bluetooth. So I was wondering... can I connect my pi 4 to my flipper with the gpio and have a massive mod. I think it would let me have access to Wi-Fi, Bluetooth, and even be able to use the video game module apps. I am pretty new to this and have no clue how all this works.
