Hm, no? Why?

https://tools.ietf.org/html/rfc4960#section-5.1.1
"After the association is initialized, the valid outbound stream
identifier range for either endpoint shall be 0 to min(local OS,
remote MIS)-1."

Section 3.3.2:
   Number of Outbound Streams (OS): 16 bits (unsigned integer)

      Defines the number of outbound streams the sender of this INIT
      chunk wishes to create in this association.  The value of 0 MUST
      NOT be used.

...

   Number of Inbound Streams (MIS): 16 bits (unsigned integer)


      Defines the maximum number of streams the sender of this INIT
      chunk allows the peer end to create in this association.  The
      value 0 MUST NOT be used.
