First of all, that's entirely possible.

You need the very basic structure of an oUF layout and use tags to display your text based information. For example, like that:

	player = function(self, ...)
		self.Name = self:CreateFontString(nil, "OVERLAY")
		self.Name:SetFont(Font, Size, Flag)
		self:Tag(self.Name, '[threatcolor][name] [hpvalue] [perhp]')			
		self.Name:SetPoint("LEFT", self, 0, 0)
		
		self:SetSize(130, 20)		
	end,

You don't necessarily need to anchor the text to those bars. The text will be moveable through oUF_MovableFrames (plugin) in game. And/or you can simply place them directly via "SetPoint" next to the HUD.

Anyway, I would recommend to build the HUD through oUF, too.
