[1.6.4 - 1.7.9] Multiversion Bungeecord

I know Bungeecord currently supports 1.7.2 - 1.7.9. I want it to also support 1.6.4 as well. I know the unnamed dude made a version of bungeecord https://github.com/TheUnnamedDude/BungeeCord for 1.6.4 - 1.7.2, but I need 1.7.2 - 1.7.9 support. Either that or I will have to link multiple bungeecord servers, which to me is a waste and I know is impossible
