Can we create Shopify's Custom App using Remix Skeleton?

Hello Team,
Is there any way to create robust Shopify Custom App using Remix Skeleton? If answer is Yes, then how? Is it the same way we create Public App or having the different process. As I am middle of the review process for Public App, not able to install it on live client store. So, I want to create the same functionality using a custom app which can be installed on any live store. So, May Shopify Remix Skeleton can be good for Custom App too? and how? What would be the exact process for the same? If Not, then How could I create the Custom App which can resolve my issue?
I am very confused in this serious matter.
I need your help to accomplish my task.
Thanks!

You can use same Remix template for custom app.

So, I want to create the same functionality using a custom app which can be installed on any live store.

Please note - you can’t install 1 custom App on more than 2 stores. This means you need separate app per live store.
For example, you need 5 custom apps to install it on 5 apps.

What I recommend?

Please make it public app to publish on app store or unlisted.
