Suggestion to make Worlds groups more even WITHOUT changing tournament format

So, I was thinking about how every year we see teams from the same region NOT get groups with difficulty respective to their seed number.(prime example is this year's FNATIC,RNG and SKT having harder groups than Splyce, IG and Damwon)

I also took into consideration that Riot don't want to change the tournament format because of technical reasons, and because they want ALL matches to MEAN something (which often doesn't happen in double elimination formats)

So, my suggestion is the following.

When the draw happens, instead of drawing TEAMS they draw REGIONS.(the drawing process is the exact same) After play-ins finish those teams are also seeded as Regions into the existing groups. (just like now)

Then after we have the complete groups of 4 regions in each group, each region's teams start to pick their spot in the groups from the available spots, starting from the Least Successful Region's Best team and working our way through all the 16 teams that were qualified.

I think this would provide more incentive for teams of major regions to want the 2nd spot compared to the 3rd spot.

Any thoughts?
