It would be awesome. If you add ideas from harvest moon, I would suggest from harvest moon - friends from mineral town. I just found that was the best game out of the series. The only thing I disliked in that game was, The days were to short, not giving the character enough time to do half of what was needed to do. Even though there was a lot more to do.
Example:
There was harvesting.
Feeding animals.
Breeding animals.
Mining.
And a few other things.
You had to use strategy just to either harvest/plant/water and feeding animals but had to leave out the rest due to lack of time in the game. If you had a lot of vegetables, You would only be watering or planting them and harvesting them all day, even with the help of the sprites you didn't get much done.
That was the only thing that got me to decide not to play that game again. If your game has a better times for each day. I will certainly enjoy trying out your game.
Good luck
