<VV> Thermister Swap?

Yes, the thermistor is not a nichrome wire. It is a variable resistor based
on temperature variations. Most NTC (negative temperature coefficient)
thermistors are a metal oxide.

Nichrome wire is used to heat up upon the application of current. Hence it
is used as the hot wire in a hot wire anemometer (aka mass air flow sensor
in engines).

I don't think the AC thermistor uses a nichrome wire; I think they used a
metal-oxide ceramic more typical of a standard thermistor.  If nothing
else, they didn't need the fast response that a air mass sensor provides
for your EFI system.
