"It would be nice if players would become interested in Nobunaga's Ambition, but as Tecmo Koei has created a lot of simulation titles, we wanted to introduce the genre of simulation games to children. It's not so much that we want them to start playing Nobunaga's Ambition as an entry point, but just as an entry point to the genre of simulation games.

Especially in Japan, the number of users of simulation games has really dropped over the years, so in order to keep people interested in that genre, we hope that kids would play this game and would take it as a suggestion of 'oh, simulation games are like this.' Then in the future they'd continue playing simulation games.

At the same time, there are people who want to start trying simulation games, well, now the games on the market are a lot more difficult, so it's a lot harder to learn how simulation games. Some new users are kind of turned off by the genre because it's too difficult." - Pokemon Conquest director Hisashi Koinuma

It definitely seems like a good idea to me. You just have to hope that the quality of the game is high enough to get people interested in the Nobunaga side of things. You don't want brand appreciation to plummet on both sides due to a poor crossover. Thanks to Immewnity for the heads up!
