so is it possible and has anyone ever done it

How does your action replay have a lot more cheats? The cheats database has a TON and you can modify it yourself to add cheats.The Action Replay wouldn't work on your R4, and you wouldn't need it to work anyway.

The R4 has it's own engine, so use a usrcheat.dat from cheats.gbatemp.net. Note that GBAtemp have many dedicated cheat code makers that only supply codes to GBAtemp's cheat database.
