user11262: Is there any way a Linux UCI Engine (such as StockFish 8) be used with Fritz 15? Will this involve customizing the source code and rebuilding to implement things like hash size, tablebase locations, and the like, or can those engine settings be set as BASH environment variables? 
I have used a program called InBetween.exe before, to act as a conduit between the GUI and the Linux engine. However I have yet to be able to get InBetween.exe to pass  UCI environment variable commands to the engine.
If someone can post an answer to these questions, I would be most appreciative.

user11691: I think you can do it using this tool ChessBridge. There's also netChess, but the website is down, so use the mirror at Archive.org.

user4509: Mixing Windows and Linux for this (and this way) might not be the easiest way. Also think about future updates that can break your working solution. You already experienced this with InBetween.exe.
If you only use Fritz as database and to analyse your games then you might consider to use SCID on Linux. It has Stockfish in it. Not the most recent version but you can easily install the most recent version.
