How to use REGEXP_REPLACE for this scenario?

Question

Oracle 10G Enterprise edition
Hi all,
Is it possible to use REGEXP_REPLACE for multiple replaces for the give text?
For eg.
select replace(replace('My oracle','o','O'),'M','m') from dual
my Oracle
Can we do this in a single regular expresion replace or suggest me any ideas?
Thanks all

This could be a solution
Processing ...
select s as string
from (
          with reps as (
               select 'aaa' as src, 'AAA' as dst from dual
               union all
               select 'bbb' as src, 'BBB' as dst from dual
          ), strings as (
               select ' bbb a sample string aaa' as string from dual
          select *
          from reps
               cross join strings
          model
               partition by ( string )
               dimension by (row_number() over(partition by string order by src ) idx)
               measures (string as s,src,dst)
               rules (
                    s[any] order by idx desc = replace(presentv(s[cv()+1],s[cv()+1],s[cv()]),src[cv()],dst[cv()])
where idx = 1
