RAC: different O_H for instances on different nodes?

Hi List,

maybe some RAC-guru can help me:
Config: 2 node RAC (Solaris@SPARC) 11.1.0.7
several DBs there, one particular
DB: CDB111T11_SITE1
Instance1: CDB111T11
Instance2: CDB111T12

currently, both instances are using the
ORACLE_HOME=/appl/oracle/product/11107 (local installed on every node)

I would like to do the following steps:
1) install a new O_H on both nodes: /appl/oracle/product/11107_PATCH
(with PSU 11.1.0.7.2 - this patch is marked as "rolling RAC
installable")
2) shutdown Instance1 CDB111T11
3) change the config for Instance1 to use the new O_H
/appl/oracle/product/11107_PATCH
3) startup Instance1
4) shutdown Instance2 CDB111T12
5) change the config for Instance2 to use the new O_H
/appl/oracle/product/11107_PATCH
6) startup Instance2
7) run the post-sql "@catbundle.sql psu apply" on Instance2

I just does not know how to change the O_H on a per Instance base;
srvctl modify seems to only let me chose one O_H per database (which
is a nonsens in my opinion).

can someone please help me if (and how) step 3 and 5 is possible?

thank you,
 Martin
