Has anyone thought of implementing a new data structure for

mempool to enable parallelization, (To run verify unspent outpoints & tx validation in parallel)?

I was thinking about what is needed to have parallel execution of transactions from the time it is received until it's added to a block. My thinking is that we have to remove the need for chained transactions in a single block. This feature adds extra (unnecessary) rules in tx verification & block creation. The solution I'm thinking involves having a new type of transaction that wraps vector of transactions in it where one can spend outputs of prior txs. And having the ability to replace these types of transactions only if they add new transactions to them.

There is a discourse website for bch developers. Initially intended to write a post there, But I wasn't able find the website.

to be honest, they are just re-tracing my footsteps of what I did from 2016 to 2020. 🤷‍♂️

This needs to be done. This is the key remaining bottleneck that prevents full parallelism so that the full performance of today’s multi- core CPUs and NVMe SSDs can be brought to bear on fast transaction and block processing. Unfortunately, this is a hard problem, because there are many edge cases involving synchronization, such as resynchronizing the mempool at block arrival and orphaning. Eventually, all the low hanging fruit will be picked and this will get done, but only if people don’t spend too much effort adding features and tweaks, especially protocol features that change and complicate the blockchain structure. When this has been done then the critical mining nodes can verify large blocks rapidly, which will enable faster mempool and block propagation. This will increase 0-conf safety and speed and will allow lowering block times while still keeping a low orphan rate. Mining nodes can afford large server configurations with extra performance that keeps orphan rates down, while other nodes can run on slower systems that can be ten times slower and still safely follow the chain.
