A freehub with spacers allows for very easy chainline adjustment, that's true, but with a bit of patience you can adjust chainline also with a SS/track hub.
But I would STRONGLY DISCOURAGE you from trying to use a vertical dropout bike for SS/FG. You're doing too many compromises for no good reason. Either get a frame with track/horizontal dropouts, or replace your current dropouts - and then USE ANY DAMN WHEEL YOU LIKE.
