Short version. Not really.
Longer version. It would likely be an incredible amount of effort and only gain you a different icon.
Prior to the DSi flash cart devs could use whatever they like and did just that.
With the DSi and then 3ds Nintendo cracked down on flash carts. The exploit they all use to work around it, and the circumstances leading up to it, is detailed in https://hackmii.com/2010/02/lawsuit-coming-in-3-2-1/
if you are curious.
While this did not at first mandate icons it is an easy thing for Nintendo to check by so the flash cart makers then had to move to mimicking the game they based their take on the exploit on (which did change between flash cart makers, and occasionally between versions of the firmware).
