I'd like to use one of the final drive ratios from a R230 with a S15 HLSD in my Viscous housing, if the parts will all fit together?

I don't understand.
It appears that you don't seem to understand that an R230 ring and pinion will NOT bolt to an R200 diff. 230 and 200 are the size of the ring gear. The R230 ring gear will be larger than the R200 diff so they are not interchangeable.
So the R230 r&p will only bolt up to an R230 diff. Same for R200 r&p and diff.
This is regardless of the case.
If you tried to put an R230 ring into an R200 case, it won't fit because the R230 ring is too big for the case.
Let's start over.
Pretend that you could mix and match or fabricate your own bearings and races and spacers, there are 4 crucial components IMHO:
1. pinion
2. ring
3. diff (the part that actually distributes power between the two wheels)
4. side flanges
There are a bunch of other parts, but assuming that those can be figured out later, at the very least you have to do the following regardless of what diff you're using:
a) the ring and pinion go together as a unit. You cannot separate them. The teeth simply will not match up. The r&p together determine the final drive ration.
b) the ring size is measured in mm. For example, R200 = 200mm or 7.9". R230 = 230mm or 9.06".
This is the diameter of the ring. Trying to bolt an R230 ring to an R200 diff will not work, and vice versa.
c) the side flanges bolt to the diff. You can mix and match the side flanges with the diff but there is no guarantee that they will fit. So you have to use the diff, side flanges, and axles from the same car.
People say that you can mix and match, but sometimes the axles will be a little off. It's best to use the diff, side flanges, and axles from the same car to make sure you have good driveline alignment.
The S15 HLSD is R200. Ignoring everything else, how can you bolt a 200mm diff to a 230mm ring? And how would a 230mm ring fit inside a 200mm housing?
Think about it for a second.

Question. What does the diff case have to do with these so-called "v8 kits"? Can you post a link?
The only thing that matters is how the propeller shaft meets the diff, and how the diff meets the axles. Everything else is internal, and provided you exercise good judgement, it will work.
What are these "v8 kits" doing that require you to use a certain diff housing?
Like I said multiple times, DSS can help you with mating the propeller shaft to the diff.
I do not recommend buying any other type of custom "kit" propeller shafts because DSS will accomodate whatever gearbox and diff you're running.
