>>5906919As somebody who has lost my use for my dominant hand for over a year, but several times of 2-3 months each time. I can say that you can definelity train your off hand. But the amount of work for it to be at the same level as your main hand is so much that is actually feasible only after you lost your main hand, and you start doing everything with your off hand. Or just decided to stop using your main hand for everything, except for what requires both hands, and even then, just as a secondary one.
Even if switch 100% to your off hand when it comes to drawing, it will still not reach its level, if you continue to do not drawing task with your main hand.
The activities which you do when not drawing influence your drawing too. Wax off, wax on, and all that.
After I regained the use in my main hand, I lost dexterity in my off hand, since I stopped doing everything with it. But all of it.
So my advice would be to focus on just one hand. And make the switch now, or wherever you need. You can train your off hand in your down time if you want, but dont expect to reach the same level as the other one. Just do it to have a easier time to transition, if you ever need to.
Another option would be to easily transition, start doing as more and more activities with your future main hand, and after you are comfortable using it for everything else, you can start drawing with it too. But that will take years
