honestly .. this idea of yours's make no sense.. him writing Naruto comic in Naruto world mind explaining why you choose Naruto off all novels your mc could have written ? .. i mean what is he supposed to say when he write about things then bam those exact things will happened well not all but ..at least 2 of them being named sannin etc etc.. its so many things that don't fucking add up its making me want to rip my hair off :P... people will eventually "find out or suspect" something be wrong and then he is ****ed royally ...
as far as I understand, you have made many "holes" ... for example, you have drawn many places that you have never been to (for example, the hokage's office ... it will remain unchanged for many years ... and there are many such places ... there there was also a hole with the theft of the forbidden scroll ... if you did everything like in the manga ... That is, you drew the moment when Hiruzen peeped at Naruto through the ball ... this is secret information ... few people know about the ball ...
