If you can afford it, and are willing to put in the time and effort
to do all of the things you elaborated on then why the hell not?

My only problem with your post is that it seems your reasoning
for wanting a twin is to help you avoid any possibility of getting
into any sort of weather. That seems sort of counter productive
in that either the 210 or the twins are very adept at dealing
with weather given a competent pilot and a some wise flight planning.
