Absolutely. 65mm on 5x4 is a whole lot wider than 24 on 35mm, as you say 19/20mm.

As decent 75s tend to be quite expensive a 90 might be a good bet as an equivalent of about 28mm. They are common and cheaper. Prob the best budget option as an older SC 90mm f8 will be a similar price as the 65 F8, but have miles more coverage and perhaps be more 'general use'.
