Your breast implant position may not be that easy to change 5 weeks after surgery. Breast implant massage, especially with both breast implants massage aggressively to the midline/ sternum/ chest plate, may help to push the implants together, or they may not.
There are a lot of variables regarding breast implant placement in the midline, including your overall tissue, your previous medical history, your smoking history, the profile of the implants, any complications after surgery, and simply how you swell and heal, so given the information you've given us, it's hard for me and others to figure out how close is too close versus too far.
I wish you the best of luck.
