ICO and standard scenario Query

Hi All,

I have one tricky query as follows.

My scenario is Idoc (Z idoc and standard also) to JMS we have this interface in production for one country. we have many scenarios of this kinds.

Now we are implementing the scenario for another country where the receivers are different, so I want to know if I can create an ICO and proceed with the scenario or should I use the old objects only (mainly Receiver determination) and modify them or I can still use the ICO?

Is it a good practice to use ICO in my condition or not?

Thanks in advance.

Regards
