I converted that 2-8-0 twelve years ago. Here's a video of one of it's first test runs after completion. It still runs great. I chose a light whistle b/c I had engines with medium and heavy engine whistles, MTH had a 2-8-0 in O gauge with a whistle like this one, and the engine in general is on the petite side. Were I to do it today, I'd choose a more robust one. In terms of S-gauge conversions, Carl T. is Yoda, Ed G. Obi-Wan Kenobi, and I considered myself an aspiring Jedi. I leveraged information on Carl's site to convert this 2-8-0, but did a few things differently and soldered components to custom-fitted boards to pull it off (very little room in that tender). At the time I think Carl had completed one which got ruined in transit to the customer, was working on another, and was going to produce and sell a kit. I did TMCC/Legacy conversions of steam, diesel, and electric engines for customers and myself over the years as well with DCC. Its fun and breathes new life into postwar as well as modern production conventional engines. Ed probably now has the most inventory of some of the key S-gauge conversion boards such as CruiseCommander Lite since Lionel jettisoned ERR and its new owners did not maintain manufacture of them.
Have fun running your trains.
