I did something like that for a website where I wanted the default 
language to be sometimes English, German or French and then being able 
to translate it into the other languages. And for this I had to create 
the English language as another possible language overlay. Default 
language being said to be French, English or German with pageTS:

mod.SHARED {
	defaultLanguageFlag = fr.gif
	defaultLanguageLabel = French
}

I then had to "remove" one of the available translation languages that 
was shown with TemplaVoila (or the default page form too but I use TV 
and as such did the stuff for it). The idea was to remove French as 
translation in this case when default language was already in French, 
leaving only German and English as overlay languages. For this I created 
a new option to mod.SHARED:

mod.SHARED {
	disableLanguages = 2
}

where 2 stands for the UID of sys_language French in my website and then 
XCLASSed TV to use this new option:

class ux_tx_templavoila_module1 extends tx_templavoila_module1 {
	
	function getAvailableLanguages($id=0, $onlyIsoCoded=true, 
$setDefault=true, $setMulti=false)	{
		$languages = parent::getAvailableLanguages($id, $onlyIsoCoded, 
$setDefault, $setMulti);
		
		$disableLanguages = t3lib_div::trimExplode(',', 
$this->modSharedTSconfig['properties']['disableLanguages'], 1);
		
		foreach ($disableLanguages as $pid) {
			unset($languages[$pid]);
		}
		
		return $languages;
	}

}

I hope you'll get an idea for your problem.
