Some folks do put in baffles between the coals and meat to guard against the grease smoke flavor. I never tried but may one day.
The only downgrade is in cooking surface from your offset. Otherwise, you will gain incredible temp control and stability, and portability you don't currently enjoy.
I wouldn't get rid of your offset until a year or two of happy ownership from a drum. I also think you'll always miss your ol' rig if you do sell!
I always use a diffuser in all my drums.
