Having messed about with rear drums, I too was ready to enjoy some rear disc action!! I wanted to keep the SPRINT alloys as I think on my road car, they are the classy option. Having read this thread in detail, I have hopefully come up with another cheap-ish solution.
I started by looking for a deep disc that would fit over the SPRINT hub but had a diameter and offset deep enough to clear the original wheel. After using the excellent Brembo website:

I found the EARLY Ford Orion 1.3 discs would fit nicely. £20 later I had a pair which were shipped straight to my local machine shop:

to have the Triumph PCD holes drilled. The centre hole and face had to be opened up and faced to match the dimensions of the original drum. £45 was quite reasonable I think!
Next came the search for suitable calipers. The Ford ones are great but unfortunately the shape of the cassting is huge and fouls the wheel beautifully
When admiring the Green Dolomite in Albert Looms scrapyard
http://www.albertlooms.com/ , Derby I found a late 90's Rover 820 sporting a pair of Lockheed rear calipers which look perfect. The car was on it's side so removal was a doddle. They charged me £20 for the pair including the very substantial handbrake cables which are a definate improvement over the original.
Having removed the axle brake back plates, it came to a trial fit up in the sunshine. The good news is they do and the required mounting bracket could be designed fairly easily. I am now awaiting a quote for the manufacture of 2 laser cut 10mm brackets. The original handbrake brakets can be cut off the axle tube which is nice! I think I'll use a Stauff hydraulic hose type clamp to secure the cables so watch this space.
