I think its a great idea. I think there should be donation stages, I will give an example.
You get your points, depending on how much you donated.
Remember, just examples,
(4,000 points) VIP Rank
(8,000 points) Unknown Rank
(16,000 points) Unknown Rank
(24,000 points) Unknown Rank
All the ranks have different colours and give you different skills, e.g, (VIP rank) 3 set homes
(Unknown Rank)(8,000points) 5 set homes and so on.
It would be a thing to look into for the future. Updates are required, it keeps the game fresh. Very important.
