No, I don't think there is any proper way to do it. You can't expand 
UI-View to show AIS as such. Without converting AIS to APRS, which in turn 
isn't really possible to do well, since APRS packets don't have the fields 
required to transmit all the interesting extra information present in AIS 
packets.

So, I think it's a bad idea to try to convert AIS (or ADS-B) data to APRS 
format, and if someone still decides to do it, it should never be fed into 
the APRS or APRS-IS networks.
