No, not at scale. There's no scenario in which this would become an economically worthwhile approach. There is no commonality between the air interface etc between Starlink and the other networks, so you couldn't reuse terminal hardware off the shelf. You could possibly reverse engineer a terminal and write entirely new firmware for it, but it's full of semi-custom silicon and so this would be extremely expensive. There are secure boot protections, so you couldn't mass deploy that firmware in the field anyway. Each would need expensive individual rework by skilled hands to be converted.
