To make a working hijack of the routed prefix (for sniffing traffic,

If you signed RPKI prefix is still unannounced - yes, somebody can
hijack it by forging the origin ASN - that's quite easy.

This axiomatically assumes first come, first serve, which is obviously
not complete understanding of BGP best path algorithm.
