Probably not a good idea. Most performance shop only carry the 180 degree model, but a 203 degree version is available from the distributor..

Keep in mind, either will constantly bleed oil to the cooler as discussed earlier:

Mocal oil thermostats are designed to regulate oil flow
through cooling devices until optimal (minimum)
temperatures are reached. Cold oil enters the
thermostat and is bypassed through the center of the
unit returning to engine (figure 1). During warm-up
the thermostat never closes off oil flow to the cooler,
rather, it offers a less restrictive path for the oil to flow*
allowing the cooler to acclimate to system
temperature. As oil warms to 180 degrees (200 in high
temp versions) the operating "waxstat" closes the
bypass permitting full flow to cooler (figure 2).
*percentage of oil bypass can vary up to the point
where the bypass is closed and full flow to the cooler
is achieved.

My Core size (similar to the Stillen) and 180 stat result in temps from 180 to 210 under most all conditions. I get very slight overcooling (175) on a cool day, cruising at speed. If I lived in a colder envoirnment and didn't track the car I think I might consider a smaller core and the 203 degree plate. This would take the edge off the temps at the high end in the summer, but not overcool in the winter...Just a thought..
