Howto change the region of a game's savefile that has a different name in each region

[MSK101.1]

I have a save file of this game Called Tokyo Xtreme Racer: Drift 2 in the US and Kaido Racer 2 in Europe and I want to change the region of the savefile from the US version to the European version and so I tried doing that by changing the game root/ID using Ps2 save builder and mymc, but it just didn't work
Any idea on how to do this?? is it even possible?

I doubt it will even work. Only a handful of games allows you to even import saves from other serials (same/different region).
