Numpad /w 2 rotary encoders, oled

Hey there everybody,

I was discussing starting a project with someone to design and build a custom numpad/macropad and sell it in a groupbuy. Here's the quick sketch I made of the layout in paint: https://imgur.com/a/xVWtN7y
Would it be something you'd be interested in? You'd have options to have a brass plate aswell, optional switches and keycaps. It would come with 2 rotary encoders and an oled screen and most importantly, the reason I wanted to make this, it would have bluetooth.

I just had a few questions:
1. Are media keys favored?
2. Any other features worth implementing?
3. Price range you find comfortable?

Any constructing criticism would be awesome.

Much thanks.
