StringResourceModel with custom locale

Hi.
I recently ran into problem with usage StringResourceModel class in
my application logic.

I need to grab value from StringResourceModel. And that value must be message for diferent locale than stored in session or inserted in component.

example:
lets have
s= new StringResourceModel(key, component, model, args);

session locale : en
component locale : en_UK
I need message for : sk_SK

i need something like
s= new StringResourceModel(key, component, model, args);
s.setLocale(/sk_SK/);

I propose
Introduce property "locale" . internally will have top priority in load() function, if is not set, it will pass next rule, witch is component and session.

if (customLocale != null)
{
locale= cusomLocale;
}
else
{
if (component != null)

{ locale = component.getLocale(); }

else

{ locale = Session.exists() ? Session.get().getLocale() : Locale.getDefault(); }

}

Thank for consideration.
