Your three items cost 6965 gold. Even when you knock that down to 4965 (the amount you'll earn over time), that's still a lot
of gold for any non-solo champ to farm in 25 minutes. Let's say you're having a good game and you get another 2000 gold from a couple lucky kills/assists, towers, dragon etc. That leaves you with 2965 to make up from creep kills alone
. That's over 130 creep kills, or, in other words, 50% of all that creeps that spawn in that period of time. Remember, you're in a side lane, with a lane mate that's trying to farm as well, and you've had an exceptional game.
TL;DR- Possible? Yes. Likely? Not at all.
