Suppose everyone is recommending these cheap heated sensors available in the US. You may not have the options quite so inexpensive.

What could be expensive is a misdiagnosis of your rich running, placing the blame on the default rich map caused by a dead O2 sensor. You don't say how you arrived at that conclusion, which I rather doubt given your extremely low MPG. I doubt this because I believe (without hard fact to back it up) the default map for no O2 sensor transitions results in maybe 22 MPG instead of 27.

You could soot up your new O2 sensor in a day's driving if that's the case.

Also LH2.4 sensors were placed at different locations, but all well out of the hot spot the unheated sensors worked well in. But a nagging thought about all that gas flowing through your catalyst makes me wonder if it isn't all that cool back there after all. Sounds like an FPR to me by the way. Or plugs?
