Can I make Starcraft 2 portable?

If I were to install Starcraft 2 in a external hard drive (changing the install folder during installation), could I run it on another computer without installing? For example, if I installed starcraft 2 on a usb, and then plugged the usb into ANOTHER computer, would it run properly? I'm fine with just offline single player mode.

Thanks

I'm inclined to say it is (having played both Starcraft II and Diablo III off of an external hard drive in the past), but... do you have a large enough USB drive?

My Starcraft II folder is currently sitting at 13.5 gigs. If you can get all of that onto the flash drive, you should be good to go.

In one of the past Intel Extreme Masters tournaments, each player was given an SSD so that they could fully customize everything (settings, OS, etc. For every match, they would just pop that SSD into which ever computer they needed to play on. You could do the same but with an external SSD like @AtlasEU suggested.
