No issues with being junior Batman, or Tony Stark / Lex Luthor left you his inheritance, your grandfather is Ra's al Ghul etc, so I'm ok with a super-rich kid. The ramifications of that societally would be obvious: the richer he is, the more likely other will know (in a world where mega-int people exist, a good number of them would be the ones controlling all the financial markets) You might need some dots in Cipher if you don't want to be known for your hacking. Lots of possibilities for storytelling, I can't wait. If you've got a high Resources or Equipment rating, I think you may need some rating in Contacts or Allies to rationalise it, your kid needs to be somehow connected or networked in order to be who he is currently. (Taking a leaf from The Directive sourcebook, an agent gets equipment because he has a certain rank in the organisation).
Inventions-wise, since I'm having everyone roughly on par to start with, I'm thinking any equipment that is the equivalent power level of the other characters' range and level of powers is perfectly fine, if you need a guideline as to how to pitch. So an armored suit that gives an armor/forcefield power, a blast, some control, some buff/debuff etc, is totally on track. or if you want them as separate devices, like a Gizmo character, works too.
But let me say again, great concept! We can have a good story with this.
