Yes you can, but first beat leafgreen and deliver the ruby and sapphire to celio then beat Pokemon colosseum, BUT you need a GBA to GCN cable to do this: Go to phenac city after beating colosseum and go downstairs in the Pokemon center talk to the lady after getting the Pokemon you want to trade from the PC. Next hook up the GBA to GCN cable to gamecube socket 2 and hook it up to your GBA(GBASP works too) then on leafgreen save your game in any Pokemon center with the Pokemon you want to trade after saving turn it off and return it on and wait for the connection to be made then start trading, to trade use the gamecube controller to choose the colosseum Pokemon your trading then say ok then using the GBA's Dpad choose your Pokemon from leafgreen then press A and confirm your choice by pressing A again and the trade begins! Happy trading!
