That’s how CDMA has always worked in the uplink while in “softhandoff”, except the packets are not combined, but “selected” (using a selector bank subsystem). that will effectively double the backhaul requirements since the same unique datastream will need to be transmitted/received from multiple non-co-located base stations. maybe they save 3 dB -5 dB of transmit power?
