Kopiez et al. (2006) analyse the relationship between one form of musical ability (sight reading) and a continuous measure of laterality with a sample of 52 pianists. They find a significantly higher level of performance by non-right-handers.

I don't think that non-right-handers means ambidexterity here.

On the matter of extrapolating behavior from particular geniuses (Einstein and company) to the general public...

I believe it is important to know whether certain forms of mental exercise, practiced over a period of years can produce genius effects in the general public.

I also think that it is important that know such things. But you can't conclude based on that genius X had trait Y that developing trait Y will make you a genuis.
The majority of people with trait Y, might be no genuises.
In addition trait Y may be a sideeffect of the factor Z that makes you a genuises.
Developent Y through through another way than Z would mean gaining no effect.

I have contemplated my own intuitive thoughts and studied both academic and nonacademic resources on the matter for over 2 decades.
I have also personally observed anectdotal results of certain ways of thinking with over 2500 private music students (from all walks of life) during this time. As a result, I am convinced it is possible for most people to learn genius behavior with sufficient training and practice.
[...]It is also a reason why the academic community validated my research through publication.

I don't criticise your "Developing-Intuition"-excercises, I think that they could work.
I think that your reasons for doing them should be: "Intution is a worthwhile trait to have".
The word left (as in left-brain) isn't even in your paper.
