I really think these types of questions are to be evaluated from the following point of view:

What actions will break the minimum regulations? What actions will also allow me to get on the ground, safely while minimizing my time in the air?

I don't know about everyone else, but if this were to happen to me, I know exactly what I'd do after I got back on the ground.

A NASA report would be filled, detailing what I did, why I did it, emphasizing safety of flight and of the public on the ground.

Real quickly though, I'm not going to make up a procedure turn on my own, albeit, it probably wouldn't be a horrible decision. . .but I'm not going to make up a procedure just for the heck of it. Especially if a perfectly useful GPS 9 approach is available (if so equipped). I can just see the write up over at AvWeb concerning an accident where a pilot generated his/her own procedure turn for an ILS approach that was radar required, clipped a tower when all he/she had to do was fly a perfectly charted GPS approach that is equipped with IAF(s) instead.
