Upgrade and split RTC instance

We have a single server for RTC 3 at the present time and would like the ability to split this off into a number of machines in the future. For example :
Now :
Server 1 - JTS / CCM / DB
Future :
Server 1 - DB
Server 2 - JTS
Server 3 - CCM1
Server 4 - CCM2
Is the above possible given the restrictions on changing server URL's ?
Accepted answer

If you use WAS as application server, you should define one of the machines (or a fifth one) as front end for the clients and there you install IHS and the IHS-Plugin for WAS.
With this you have one central URI and the IHS-Plugin will distribute the calls to the correct context.

Yes this topology should be possible. See link
You can check the Reverse proxy articles so that the server url is redirected to the new servers
