Okay if I understand you can't make a big print?
The problem isn't likely the condensor setup. You might need a recessed lensboard. You might need a flat one. Basically you need the lens closer.
If you have an 80mm it'll work with in reason. Really big prints will mean you'll have the head higher up and the enlarger might shake.
A shorter lens will only give you the same problem you get from the 50mm but earlier.
