You are right with what you say but I just meant that the average confirmation time would be quicker since many people just pay 1-2 sats/vByte and this transactions will also then get processed pretty quickly.
Sounds like you just want every transaction in the mempool to be confirmed in the next block, regardless of how many there are or what fees they pay. There are already various forks of bitcoin which do this if this is what you are looking for, although be prepared for your money to be worthless since they all constantly devalue against bitcoin since nobody actually uses them.
It was also planned to upgrade the block size by satoshi but since he disappeared it never happened.
It did happen. The limit on the block size was increased from 1 megabyte to 4 million weight units. This gives a theoretical maximum size of 4 megabytes, although the largest actual block we've had so far, block 682,482, was 2.4 megabytes.
