triple boot AmigaOS3.9-AmigaOS4.1 and MorphOS 1.4.5 would be your option E but after reading your option C,
"C. I have a moderately busy life and, unless it is REALLY important, can rarely afford to run around chasing fixes to things over hundreds of different forums."

consider also that the current MorphOS 1.4.5 for classic is outdated. You will need to update to MUI4 and some others latest components as well.
in few words .... you will need some tweaks and free time.
