load cell input on thyristor input

[electrichg]

I have a project on which I am using a data logger.
The data logger has spare inputs for temperature that I am not using. I need to log the out put from a load cell (0.5v-4.5v) but the data logger does not have an input for this.
Is it possible to design a circuit that make the 0.5vto 4.5v output from the load cell appear like a 30k to 0.67k out put from a negaative temperature coeficient thyristor so that I could log the load cell on a temperature input?
0.5v~30k
4.5v~0.67k
control voltage 5v
1/R proportional to loadcell output

Thanks
