MVP Built. Plz help me to decide whether to develop it further

Background

I was getting self obsessed and also motivated from the IH's quotes such as

"Ship stuff. Building a product and showing no one is the easiest thing in the world."

"Start small. When you're just getting started, make sure you get a few small wins under your belt."

You can find them here (https://github.com/sakuag333/IndieHackersQuotes/blob/master/quote_dump.txt).

So I started to be productive in this lockdown situation and found some time to work on a small hobby project.

Idea

I was trying to find something that I can create using React. I found Gatsby is quite interesting and can be the perfect option to work with. So I tried tinkering with it and developed a simple website using React+Gatsby+Google Sheet.
Once I built, numerous ideas came to mind about how I can give shape to this simple idea is so that it is helpful to nocode users.
However, as you can guess the idea is not new and is quite old by now. Because of this reason I was very shy to post this on IndieHacker.
But, I thought if I can give the user plenty of option to customise their website from the google sheet itself, this can be something that I can offer them.

For example,

1. using one template they can customise the website from googlesheet itself. Giving them the complete power of creating blazing fast static websites from google sheet.
2. having plenty of other templates as an option to create website, just by deploying it to Netlify.
3. giving them an option to fully own the website code. Every website will be a standalone static website which they owns fully. Initial set up and deployment will be done by me.

USP

1. Users fully own the website, as it will be not a SAAS product.
2. For most of the template, there is no need to use a CMS.
3. Stand alone website, the user has full control of customising it in future.

I want to know

1. how to give them an option to create new pages and edit the post from the google sheet? Should I connect a CMS for such templates in which editing and creating new pages are required ? Or should I just stick to those templates that doesn't require creating blog pages (as this modification can be done latter)?

2. should I go for building this fully based on the above?

3. Your views on this. Please leave your comments and feedbacks on this. I really want to know what the community feels about this. Or if you want this to be created please let me know your inputs. Also if you feel that you can give this idea a shape and be a part of it, please let me know.

Thanks
