The epilogue from the artbook is just Heero trying to change his name and Relena making a garden for him after they have been married for 5 months, Relena mentions having children and they embrace in the garden during sunset, the end. Doktor J is alive(99 years old) and there's a mention of a Vampi...

Has anyone gotten to take a crack at the epilogue in the artbook?

I also find myself wondering what Alpha!Heero's been calling himself all these years, lol.
