You should not change your piercings until they have fully healed. There’s a fair chance this could be slightly past the 4-6 weeks your piercer has recommended - not to mention that it’s also an actual open wound, so you’re introducing new bacteria into it hence increasing the risk of infection (which can lead to further complications down the line).
I’ve recently had my ears pierced too (helix and lobe), I’d love to change them, feel your pain. But now isn’t the time, no matter how urgent this feels. If you’re still seriously considering taking them out I’d contact your piercer and tell them about your situation, but I’d put fair money on the answer still being a firm “no, you’re asking for infection”.
