I could answer this with one word, but then that could be taken as spam, so now that I've prolonged the answer, the answer is nope. If you're wondering how to get pokemon that are obtained in Johto, serebii has all the answers

Well I'll tell you. Go to serebii. Look on Fire Red/Leaf Green. Look on the right side which shows sections. It'll also show you a bunch of Islands
