Don't sell or trade away your present kit for a new format, you'll likely regret it.
I suggest you look for a Speed Graphic 4"x5" or, a 5"x7" and shoot that for awhile, using paper negatives when film is too expensive, for day to day shooting, especially in public, where you want folks to stop, watch you and ask questions, giving you the opportunity to shoot portraits, a true objective for your public use of the Graphic.
The trick will be to learn how to set-up the shot quickly for rapid documentary work and, the resulting photographic works.
Folks get impatient quickly, this the need to compose and shoot, in situ, which will sharpen your skills, hopefully getting good, fresh shots most any day.
IMO, it'll be a good "project" and good fun.
