I'm a lefty but play right handed. I have played left handed for about one year (in parallel with my right hand playing), and though it took some time until I got used to it I have made good progress. I would expect that in the long term (!) it will be easier for you to change your playing from right to left. In concerts I see many professional players that use excessively p, i and m, like Ana V. who plays a tremolo with i and m only, and I think many pieces can be played either with p, i, m only or by using the pinkie.
Happiness is when what you think what you say and what you do are in harmony.
