Remake option for mid/late game

I had most frustrating game ever recently. We stomped botlane, our Vayne got fed and was solokilling people from enemy team at will...and then she DCed. And didn't comeback. Of course, 4v5 is winnable but with Vayne having majority of our teams gold we were in a really deep hole from that point on and enemy team basically choked us out because we had no way to deal with their splitpush.

It's awesome that we have remake option - but is there a chance we can extend that option? Let's say, if someone on your team DCs for more than 30 seconds after 15 minutes? It really sucks when you are forced to play 4v5 only because that DC happened after first 3 minutes :/
