CAVE WORLD INTO INFINIT:A QUESTION ON BETAS

Right now, I'm making a game named Cave World,no connection to Cave Story. It's about a kid who goes into a cave known as the dark world, and finds monsters hidden in each part of the cave. Not that far in it.
I was going to make a game by the name of Infinit. It was about a group of orphans, all related, who end up leaving when they find out they have powers, and are chased by the government.
Now, I watched a video today, and it brought back memories of Infinit, constantly using the word infinite. I've ran into problems with doing more than one project at a time, and I don't seem to like the idea of doing these 2 at once. So, what about merging? Neither of these games are out yet, never of even started Infinit officiallly, besides making a site. How could a horror game about a kid in a cave, and a sci-fi game about orpans come together? Well, I want to ask you these questions.
Have you ever thought of merging a past game yoe never finished, with a game you're planning to finish? Do you think it would be a good idea?
And what would be the name for such a game?
I hope I put this topic in the right section, and I hope questions are answered. :3
