Not entirely easy. SFPs and FPGA's need to be in the mix, software patches, power supplies, etc.
Why? Worst case, couldn't you put the Starlink terminal, router, power supply and all in position A, together with a (worst case) Wi-Fi to fiberoptic Ethernet bridge running to position B?
The Starlink terminal is already a giant transmitter, after all.
You can loop the fiber to a far of location of the rest, no need to be point to point.
