Got it simplified to 
type WithErrorResponse<T extends Endpoint, ErrorType> = T extends {output: infer O}
    ? O extends string | number | boolean | null | undefined
        ? Omit<T, 'output'> & {output: O | ErrorType}
        : Omit<T, 'output'> & {output: O | ErrorType}
    : T;
type AddToAllSchemaOutputs<S extends Schema, ErrorType> = {
    [K in keyof S]: {
        [M in keyof S[K]]: S[K][M] extends Endpoint ? WithErrorResponse<S[K][M], ErrorType> : never;
    };
};
export type AddToAllOutputs<T extends HonoBase<any, any>, ErrorType> =
    T extends HonoBase<infer E, infer S> ? HonoBase<E, AddToAllSchemaOutputs<S, ErrorType>> : T;
type WithErrorResponse<T extends Endpoint, ErrorType> = T extends {output: infer O}
    ? O extends string | number | boolean | null | undefined
        ? Omit<T, 'output'> & {output: O | ErrorType}
        : Omit<T, 'output'> & {output: O | ErrorType}
    : T;
type AddToAllSchemaOutputs<S extends Schema, ErrorType> = {
    [K in keyof S]: {
        [M in keyof S[K]]: S[K][M] extends Endpoint ? WithErrorResponse<S[K][M], ErrorType> : never;
    };
};
export type AddToAllOutputs<T extends HonoBase<any, any>, ErrorType> =
    T extends HonoBase<infer E, infer S> ? HonoBase<E, AddToAllSchemaOutputs<S, ErrorType>> : T;

I got something working with 
type WithErrorResponse<T, ErrorType> = T extends {output: infer O}
  ? O extends string | number | boolean | null | undefined
    ? Omit<T, 'output'> & {output: O | ErrorType}
    : Omit<T, 'output'> & {output: O | ErrorType}
  : T;

export type AddToAllOutputs<T, ErrorType> =
  T extends HonoBase<infer E, infer S>
    ? HonoBase<
        E,
        {
          [K in keyof S]: S[K] extends {[method: string]: any}
            ? {
                [M in keyof S[K]]: M extends `$${string}` ? WithErrorResponse<S[K][M], ErrorType> : S[K][M];
              }
            : S[K] extends object
              ? AddToAllOutputs<S[K], ErrorType>
              : S[K];
        }
      >
    : T;
type WithErrorResponse<T, ErrorType> = T extends {output: infer O}
  ? O extends string | number | boolean | null | undefined
    ? Omit<T, 'output'> & {output: O | ErrorType}
    : Omit<T, 'output'> & {output: O | ErrorType}
  : T;

export type AddToAllOutputs<T, ErrorType> =
  T extends HonoBase<infer E, infer S>
    ? HonoBase<
        E,
        {
          [K in keyof S]: S[K] extends {[method: string]: any}
            ? {
                [M in keyof S[K]]: M extends `$${string}` ? WithErrorResponse<S[K][M], ErrorType> : S[K][M];
              }
            : S[K] extends object
              ? AddToAllOutputs<S[K], ErrorType>
              : S[K];
        }
      >
    : T;
you can then do 
type ErrorType = {
    success: false;
    errors: {message: string; code: number}[];
};
export type App = AddToAllOutputs<MyApp, ErrorType>;
type ErrorType = {
    success: false;
    errors: {message: string; code: number}[];
};
export type App = AddToAllOutputs<MyApp, ErrorType>;
