Perhaps if you were on a flat open surface, you could plot location
and signal strength from many data points, and extrapolate the centerpoint.
However considering uneven terrain and trees, buildings, etc
your uncertainties would become large. Unless you had perfect
knowledge of the surroundings and reflections it becomes
not impossible perhaps but very very difficult. Wonder why you
would deliberately try to swim in a straitjacket.

Directional antennas exist. Time is money, instead of
taking many time-consuming readings for hours and solving
a complex problem.....
