Is anyone interested in fast magento api solution?

There are lots of e-commerce solutions in market, but still many people using magento for their store in headless way and thing is it's not going anywhere. From my past experience working with clients using magento, the major pain points are slow api response, high cost of developers, integration with external apps. So, my idea is to provide a graphql api layer directly on top of mysql (or mariadb) instance of magento with 1:1 mapping with official one written in go or node.js.
This will solve the api performance problem due to magento using php and xml which are the main cause of slowness in api. (XML vs JSON).
With this, one can simply host magento like this (which will reduce cost):

• A single small magento server for content team only.
• An external self-hosted AWS or google cloud MYSQL solution.
• A fast api SaaS solution on top of mysql.
