I do not like the changes proposed here, they are all crying out for several round cleanups and modernization. One thing that would help is to split this up into a series of changes that could be evaluated, e.g. the use of regex may be a significant part of this so maybe start with that, report back, then work through the iterations to make it clean and maintainable.
