You just need to release a remastered version of one of the classic PES' parts. Whether PES 5, 6, 2008, 2010, 2013, 2014 - it doesn't matter.
If you release it, the gamers will forget the whole negative over eFootball 2022.
Also, you do not need to purchase additional licenses, as you do already own them.
This project will gather old/new fans around the game. It will be great, and everyone will forget FIFA if they can go back in time and play for their favorite team once again. (Not as "iconic players" in FUT mode)

Look, your managers receive thousands of dollars for crappy ideas that ruin your reputation, but I give this tip away for free because I love this game, and I know what I and thousands of other gamers would love to see.
It's a great shot, don't miss it.

If you don't want to release a separate game or don't have a budget for it, you can release a DLC of a particular season,
Furthermore, you can release a DLC of a particular season with each part of eFootball.
For example: with eFootball 2022 you can release the DLC of the season 2001-2002.
With next part, eFootball 2023, you can make a DLC of the season 2002-2003, and like this...
The time range could be 20, 15, or 10 years. That's up to you.
About the name: you can call it just "Pes season 2002-2003" or "Back in time: Season 2002-2003" or "Back to the season 2002-2003".

This DLC will give you additional (previously projected) revenue.

And the last please stop working for zoomers. As they are kids and glory-hunters that they flow by the mainstream. Fifa is the mainstream now! Realize this! From lads in bars to teenagers in schools, every single glory hunter plays Fifa. It's a fact.
They know that others play, and they do want to be like others. The only way to have some fame is by releasing a good game. Like it was with PES 2007 or Pes 2010. Please, stop trying to invade the wheel again.

Only if you become the mainstream futsim - the zoomers will come to you. In all other cases you will lose your fans.
