Any luck with the rpa / archiving thing to bypass the Android limits?

Alright, so it turns out that Android builds are natively built without the RPA files. Theoretically, you should be able to drop the newly purchased RPA file into the "game" directory where Android installed your version of WCA and gain access to the character just like on PC. Will have to test with a free DLC character, I think.
