The idea that you need a mesorah in order to do a mitzvah is one I find quite silly. Put aside everything for a second and think about it. If the Torah says do something then its a mitzvah to do it. It’s really as simple as that.
However, in order to passkin lehalacha that one is obligated to do anything you MUST follow the structure and rules of halacha which may very likely require case precedent. The evidence of techeiles is purely scientific. there are no halachic tools available today to poskim which allow them to weigh this science. Therefore there is no way, without what you call mesorah, to pakin that one must wear techeiles.
Since there is no aveira involved in wear blue and science suggests you are doing a mitzvah then why not take the chance that maybe you are doing one?
