There is already a Lightning Network and some side networks that support Bitcoin and USDT tokens, so you must make a comparison between what you are trying to provide and the solutions currently available and what makes you superior to the liquidity network or the Lightning Network. The problem of high Bitcoin fees will require many solutions, but there are solutions in the market, so it is necessary to present your idea in depth.
I think when it comes to technology, every idea is worth bringing to live, and in the end, the best one would lead by getting the highest patronage while the others will act as an alternative if they are worthy to be kept, else, they can just die off and be forgotten like the hundred of thousand of shitcoins that came with different ideas but today are no more.
And speaking of lightening network, not very many people are using this at the moment, and sometimes I wonder if its because people are not aware that it exists.
So, if what op is proposing is something that will capture the interest of alot of people, and contribute in it's little way, in the adoption of bitcoin as a means of making micro payments for goods and services, then why not, let him build the idea and bring it to live let's see.
