Actually, on my Pearl Version(which I never got the National Dex on, but have a ton of 'National Dex Pokemon' from my Diamond on it) the Numbers are just '???' Although, I haven't tried to breed them...
But they'll most likely do something like they did in Fire Red & Leaf Green (have key items that will allow you to trade with D/P/Pl [Guessing a 'Diamond' and a 'Pearl' since in FR/LG it was a Ruby & Sapphire used to Power Bills Machine])...Until you get those, you can only trade between HG/SS, but if you have both, and one doesn't have the National Dex, and the other does, and you trade something from the National Dex, you'll probably get the '???' over the numbers, like in D/P/Pl
...I need to play less Pokemon
