If the page title is 60% of the oomph to your SERPS, then changing it just keeps changing the keywords it ranks best at.
What on earth are you trying to achieve?
If you let us know, we can help a bit more!
if you don't - well go ahead - keep changing it, and let us know what it tells you!

OR, are you thinking that by doing this that you can get the same page spidered a multiple of times for the different search terms?
Sounds very risky to me however if you do try it out let us know the results.
