Actually, you can, but you have to have patience and luck.
First you'll need Mocha and WUPinstaller in your SD card, then you exploit it up using your favorite webexploiter. If you have success, run Mocha. After going back to the main menu you'll need to exploit it again (that is the luck and patience part). If you are lucky enough to successfully exploit twice in a row, you can finally go to WUPinstaller and install normally your CFW games, like VC and other e-shop games.
Hope it was helpful, have fun!
