You could do that, sure, in your own copy of prototype.js; just search
for Ajax.Request and modify the initialize function. You might be
able to do it in your own code after loading Prototype by replacing
the Ajax.Request.prototype.initialize implementation, but that gets
tricky. Either option is (a bit) fragile, as it will require
maintenance when Prototype is updated.
I'd probably go with search and replace.
