Need Help With Combining Genres

Hey guys!
I’m an electrical-electronics engineer and i started to develop a new android game. The thing is, my game’s genre: I want to make a simple tower defense game with Unity just like “Jelly Defense” however i’d like to add a tycoon part to gameplay. In short i want to mix tower defense and tycoon game genres in one but i have no idea what i’m supposed to do. I even don’t know whether it’s possibble such a thing with Unity.
If somebody helps me, i’ll appreciate it.
Thanks!

It seems more of a game design problem then an engine limitation.

You can do whatever you want in Unity; it’s a matter of programming it.
