Timber Peak and the Original LNOE to mix or not to mix?

[Apocalypse]

Now with BitF, I have finally split my decks. If I'm playing a TP or BitF scenario we play with those 2 decks combined, any other scenario from base game, SotF, or GH is all Decks except those two. My theory is it will play well as the 2 deck combo has specific cards revolving around the XP system, whereas the other decks do not. I feel it gets more of the cards that actually pertain to that setting out in play. Although a defend the manor house using Forest ring, grave weapons and zombie champions, and XP sounds like quite the intense battle...
