CZ,
I think your idea of the single shot falling block rifle fits in nicely with, what I consider to be the best made, and best looking falling block rifles, that is, those made by George Gibbs. The ones I have seen by him were very nicely presented, and in "stalking" calibers, as opposed to heavy knock down calibers, the G,Gibbs rifles were of course made by Gibbs, whereas a lot of the trade Farquharsons were Foreign made in the white, and finished in Britain by the outworkers for retailers like W,J,Jeffery, the standard of work on these trade rifles was quite a lot lower that the G,Gibbs made offerings, even some of the Webley "made" rifles have been quoted as being of Foreign origin, and there was a huge court case mounted in the 1800 about this. Westley Richards build their 1895 action in everything from rook rifle to Elephant stopper (I have one in .577 NE)but I think the G,Gibbs Farquharson was by far the best, as is born out by the fact that people actually paid the equivalent price of a basic double for them. Get one,they are very nice!
