CUSTOM PRIZES. A window to great possibilities?

[fenometrix]

How possible would it be to have customization in the prizes?
I have thought that it can be a small incentive for the casual player, but a HUGE possibility to organize some game to interact with the audience and that the Streamers use it as a game to award real prizes. I explain myself and expose more than one form of customization that can perfectly coexist.

CUSTOM PHOTO
Have the option to create your own gallery of prizes where you can choose shapes and colors (square cushions, star-shaped, spheres) and add your own photos from the gallery to be added to the game graphic. You could also use the shape of some objects and animals, maybe a belly, or a stuffed human where their faces appear.

For a Streamer: He could create his own custom object gallery and add pictures of prizes: x1 free sub, x1 funko pop, x1 Steam code etc.


CUSTOM TEXT
Similar to the previous point, but instead of uploading your photos, you can create a gallery with objects with TEXT and editable NUMERICAL FIGURES. This way, you could create some kind of competition based on the points obtained by adding the numbers or letters of the objects.

CREATE YOUR OWN MACHINE
Related to the previous point, once you customize your prizes, have a “personal machine” where you can load the amount and probability of each object, as well as being able to configure slightly, for example, the weight of each object and the strength of the machine, even progressively (For example: Acquire progressively its maximum strength after 10 failed attempts. When it wins, the force is reset again and goes up slightly at each attempt until the configured number is reached.


Surely everything is more complicated and unfeasible than it sounds in my head, but I wanted to leave here these ideas that have been coming to me playing the simulator.
