Asymetric multi-homing configuration

Greetings,

I have a question about this. For reference, I'll use the following from
section 7.4.2 of the SCTP Reference Guide by Steward and Xie:

Host A                                                         Host Z
+-----+                                                        +-----+
|     |              +---+      ************                   |     |
|     |--------------| R |------*          *                   |     |
|     |1.2           +---+      *          *      +---+        |     |
|     |               1.1       *   IP     *------| R |--------|     |
|     |                         *  network *      +---+     3.2|     |
|     |              +---+      *          *       3.1         |     |
|     |--------------| R |------*          *                   |     |
|     |2.2           +---+      ************                   |     |
+-----+               2.1                                      +-----+

"R" = router


Host A routing table               Host Z routing table
====================               ====================
Destination    Gateway             Destination    Gateway
-----------    -------             -----------    -------
3.0            1.1                 1.0            3.1
                                   2.0            3.1

The contraint here is that Host Z cannot have an additional address.

Assuming the route in Host A routing table is the "default" route, would
an additional "static" route help achieve multi-homing?

Host A routing table (proposed)             
====================
Destination    Gateway
-----------    -------
3.0            1.1  (default)
3.0            2.1  (static)
