Give it a shot. You might also want to consider some of the softening filters on the market. I've had the same problem in the past myself.
The great thing about cameras like the Mamiya TLRs and other old cameras is that they can give you another "look" and be pretty cheap too. I use mine as my only 6x6. That way I have a format option as well as a lens option.

In fact outside of my N80 and Pronea 6i I don't have anything from the last two decades...hell, the last THREE decades that I use really.
