Until Blizzard dropped the bombshell that the Draenei and the Eredar were in fact the same race. In 2.0 the sentient lost ones in the swamp of sorrows were retconned to have the Broken model introduced with the expansion.
As for your RPG plan...if the broken and the lost ones could slip through the portal I see no reason why a full blooded Draenei couldn't if he was careful enough.
