You're clearly making a nice chunk of change already if tax-avoidance alone will net you $1mm extra. This plan seems very "Panama Papers"-y and unnecessarily greedy to me.
I can understand if your government is highly corrupt or something, but it seems distasteful to me to take advantage of the strong safety net, schools, etc. that are funded by a high tax rate, then once you've become successful to try and dodge your responsibility to give back to that same society.
Just my 2 cents -- you do you.
