Uh, no, more than enough to make it remotely unfeasible. There are tons of variations of the letters in "google" and with all its permutations + all the TLDs, I wouldn't be surprised if there's at least a few million domains. With all the new TLDs as well which are extremely pricey, the costs for this aren't a joke.

And don't forget that there's an endless amount of misspellings and word variations (googleapps.com, ...).
