Is it possible to change the GAME ID of a particular game or change the GAME ID of a DLC?

Hello again people, I have kind of asked this question in the PS3 Gaming thread in a quite similar way but got no answers. So I am moving it here and changed the question a bit.

A bit of info first! I have Need For Speed Hot Pursuit. Its GAME ID is BLAS50277. I think its an Asian/Chinese version. Now this version of the game is like a ghost. I couldn't find much info on the web about it. All sites are Chinese/Japanese/Korean, I don't know for sure. The problem is I wanted the Super Sports DLC for the game (the one with the Bugatti Veyron 16.4 Super Sport.) And my country (Ethiopia, East Africa) has no PSN, so I can't download the DLC via the PS Store.

So I just googled for the DLC on the web. I got it but it was only in two versions: BLES00949 and BLUS30566. The first one, I think, is an European version and the second one is an American version. No Asian version with the BLAS50277 ID.

I downloaded the European version (BLES00949) and installed it to my PS3. Obviously it didn't work. I went to my PC and extracted the DLC's PKG file. I got a bunch of folders. From there I noticed that all the languages are the same. Meaning, BLES00949 and BLAS50277 have the same languages. Not one more, not one less. All languages are the same. I thought all the other files must be the same too since they are core game files (vehicles, tracks, textures, sound and videos).

The DLC's PARAM.SFO and my game's PARAM.SFO are different. The EBOOT.BIN file from the DLC and the game is different too both in size (the DLC is bigger by 0.2MB) and MD5 checksum.

Now the question is or my questions are:

1. Do you think these two versions of the game (BLES00949) and (BLAS50277) are similar (except for the SFO and EBOOT)?

2. Can I change my game's GAME ID to BLES00949 and make the DLC work? Or can I change the DLC's GAME ID to BLAS50277 and make it work on my game?

3. If your answer to my second question is YES, then how do I change the GAME ID? I know I must change the PARAM.SFO and PS3_DISC.SFB files but do I have to mess around other files too (like the EBOOT.BIN)?

Thank you for your time!

P.S: If this works, its gonna be my first ever DLC!!! :)

uh? well, i guess it might be possible but is way harder to do than you think, an easier solution i can provide you is to create an account from another country from Asia that has PSN Store and buy some PSN Cards from that country, usually every Asian country uses the same GAME ID so i think that should work for you
