Anupam, you're right that a reversed lens' native mount is irrelevant. And yes, if you can find the right step rings or have one made to fit, you can screw a reversed cine lens right on the adapter(s) and then on to, say, a BR-2, as you suggested.
A bellows gives variable extension, extension tubes give extension in fixed increments. But not all tubes in a system are the same length, so it is often possible to get nearly the desired extension (= nearly the desired magnification) with tubes.
FWIW, I don't use Nikon F-mount tubes, they're too expensive and too short. I use E. Leitz New York (ELNY) tubes with mount adapters at each end; I have around 30" of them. The only problem with using non-Nikon F-mount tubes on a Nikon is finding an adapter to attach the string of tubes to the body. I have a couple of Novoflex NIKLEIs and a real Nikon El-F, but these things are rarely cheap and not too easy to find.
And if you can get the right adapters there's no reason to use a Nikon F-mount bellows. I have three bellows, probably use the Zenit (?), which is M39x1 at both ends, most. Also sometimes use a Minolta Compact Bellows, with other adapters. But if you don't want to spend the rest of the year chasing adapters or to buy them new at new prices, get a bellows in Nikon F-mount.
What you do want in a bellows is one with a moveable front standard or with a front standard fixed at the front end of the rail. Otherwise you risk the front of rail interfering with your subject.
I think you can get -- no promises and I'm not going to go shopping for you or give you anything -- , say, a 25/1.9 CE II, step rings, BR-2, and a bellows that will do for no more than $100; I'd be surprised if you had to spend more.
