What could be the most convinient and minimal way to power and use iPad as a soundmodule?

Hey, I'm looking for a way to use iPad as my main synth- and soundmodule with a midi keyboard.
I'd say the most annoying part is figuring out the connections and powering the device.
Right now I have to use a dongle for already 3 connections needed- Power (from a powerbrick), usb from keyboard and audio out. I don't like this.
What could be the best gear and option for minimizing this?

THE IDEAL would be- midi keyboard with its own power, having an internal audio interface option and at the same time powering the iPad. And it would manage all 3 connections (power, audio and midi signals) with one usb-C connection from the keyboard. I'd just connect my iPad and it would be ready to go. The volume control would also be managed from the master volume dial etc.

I have looked two keyboards with audio interface capabilities right now-
Yamaha CK line (ck61 and ck88)
and Studiologic Numa X Piano 73 or SL73 mk2

At first I thought that with these it would work exactly as I described, but I think I'm wrong in the fact that for example SL73 would actually TAKE power from the iPad, not vice-versa. Would it be the same with the forementioned Yamaha keys or the Numa Piano? (They have their own power adapters, but would they still have the oomph to power iPad aswell?)

Edit: to clarify, I mean hubless options- could the keys act as a hub aswell for managing all the connections

    Hi. Assuming you have a USB-C iPad, the power question is not just about "oomph". A device can only supply power to the iPad if it implements USB-C Power Delivery. This uses some extra pins in the connector to feed power upstream to the host device. It will be difficult to find a keyboard that implements this, since it is easily implemented by hubs or dongles. If a keyboard does this, it will be mentioned explicitly in the specs.
