1.) StreamAliases are only used for playbacks so in this case:
a.) pull your stream, give it a localstreamname
b.) at the localstreamnames parameter, you may put there the localstreamname of your pulled stream. This will make your createHlsStream command use the localstreamname assigned for your pulled stream for creating HLS.
