Because the 737 classic's engines stretch out much further forward than those on the original 737 (100/200), the 737-500 isn't able to accommodate a cargo door the way the 737-200 was. I suppose it could be done - though it would be difficult and might involve moving the crew entry door forward - but nobody has and probably nobody will. There are good reasons for that.
Chief among those reasons are the door/loading problem and that you can buy a 737-300 for about the same price, and given the availability of conversion on that frame coupled with it's larger size and capacity, it's just a better fit.
Here you can see that the cargo door stretches right up to the leading edge of the wing on the 732 (a conversion, not a 732C) and what a converted 733 looks like. There's room to load safely and comfortably, but not all that much. The extra pallet conversion is even tighter.
(Apologies for the self-plug).
Though the 732 is even a little bit smaller than the 735, it was more commonly available as a QC/Combi, as there was more demand for new-build QC's in the 732's era - meaning that those that were built that way are easy to press into service as freighters. The ability of the 732 to handle special missions like those of Air North has also preserved it in a way that the 735 probably won't be.

I'd say why ??
The 733 as is has pretty poor economics as a freighter with the 734 the best of the bunch, the 735 would be atrocious.
Since you are essentially paying similar operating cost of the 735-733-734 serious, you'd want to get the bird that can produce the most revenue. (and reason why the 735 was not s stellar success amongst passenger airlines either).

Boeing built 104 732C combis with a main deck cargo door.

@CargoLex: thanks for the input. I forgot how much the CFM56s extend forward of the leading edge.
I was just thinking that sooner or later cargo airlines Aloha Air Cargo is going to have to upgrade from their 737-200Cs, and what would replace it. With the longer load & unload times for freighters, I don't think Aloha Air Cargo will experience the same issue with the CFM56 as their predecessor, Aloha Airlines had when they had pax -300s and -400s.
Toll/Airwork NZ has had a few of their 737-300Cs pass through HNL on delivery flights.
