Feasibility question: 2 SDR dongles + dump1090 + ATCLive on the same Raspeberry Pi 4 (4GB)

Hello to all! I want to use an RPI 4 (4GB) board for receiving at the same time ADS-B data (probably using dump1090 + Flight Aware 1090 dongle) AND ATCLive (Using https://github.com/szpajder/RTLSDR-Airband) + a cheap RTL2832 SDR Dongle, both streaming at the same time.
