If I understood you correctly, real issue you have is not about Airbus controls per se but about having to steer the aeroplane with one hand only.
It's not a problem at all. Even if you fly aeroplane with yokes, horn for your inboard hand is used only on takeoff and initial climb. For all the other flight phases, outboard hand is on yoke, inboard on throttles. Captains fly with left hand, first officers with right, type rating instructors (or line training captains) use whichever they need, depending whether they instruct future capt or F/O on particular day.
Personally, I went from from flying C-172 with left hand to ATR-42 with right to A320 with right to Q400 with left. Never had any problems adjusting and never heard of anyone who had.
Apologies if that is not what you asked.
