Trade away Texeira for Halladay?

[mcelvis]

Below is my line up in a roto league. I'm currently near the top in hitting categories, but lacking severly in pitching (other than saves). I need W's, K's, low ERA, and WHIP. I figure I might be able to sacrifice a little hitting for an ace.

Should I trade Texeira for Halladay? THANKS!!

Other option I have available is trading Bay for Gallardo or Edwin Jackson.
