BungeeCord and MCPC - working?

Hi all,
I wonder if it is possible to setup bungee cord to work with a mcpc plus server (to use forge mods + bukkit plugins) ?

I am trying to achieve this:

proxy (bungee cord)
server 1 (spigot)
server 2 (mpcp plus)

or at least this:

proxy (bungee cord)
server 1 (mcpc plus)
server 2 (mpcp plus)

Thank for your help!
