That's roughly the list of things to consider, yes.

That's a *very* slippery road. You need to save more state than just the 
markup table itself - you'll have to save the entire state of the 
substitution process, restart the substitution process with the new 
table from scratch, and then carefully restory just enough of the saved 
state that the engine will continue seamlessly.

It's very difficult to do stuff like that and get it to work.
Worse, it's impossible to foresee what future changes in PmWiki might 
break it.

I strongly recommend against taking that route.
