If you made more tham the max , to be legal and to stay within the TCDS , would you just have to get the carb, adjusted down , to limit the max static RPMs ? Is that correct ??

No, because "adjusting" the carb would violate the carb specs and would also not be approved. The TCDS specifies "at max throttle" for determining static rpm. To be legal a different basis of approval is necessary. This might be nothing more than a field approval or it might require an STC. Visit with your FSDO and Prop shop, as I'll bet they've already invented this wheel previously.
