If you are prepared to change the complete document font, yes.

* The package "fourier" offers nice mathematical fonts to match the Utopia
  text font. It comes with an upright integral sign.
  http://www.ctan.org/pkg/fourier
  
* The package "txfonts" (and some more packages using its fonts) uses a
  "bulky" upright integral sign.
  http://www.ctan.org/pkg/txfonts
  
* The package "newtx" is an improvement over txfonts (re-worked metrics)
  and offers a customizable integral sign (txfont or slanted).

* The package "mathdesign" uses an upright integral sign as well.
  It can be used with "Utopia", "Garamond", or "Charter" text fonts.

* The in-line integral sign in "mathabx" is even backward.
