BITOGers, what should i do?

For my wife's '97 Expedition 4.6L - 108k mi., I've got the following oils (& a MC filter) sitting in the garage:

(11) qt's. Havoline Synthetic 5w30
(4) qt's. Havoline Synthetic 10w30
(5) qt's Quaker State Peak Performance 5w30 conventional
(1) qt. Castrol Syntec blend 10w40

I have to change the oil in the next few days. The Expedition takes (6) qt's. of oil with filter change. It has a history of burning (1) qt. of conventional oil every 4k miles. It does not leak any oil.

FWIW, I had been planning on using the (5) qt's QS + (1) qt. Syntec Blend for this oil change. Is it ok to mix the two? For that matter, would it hurt anything if I mix a little of all of it?

Sounds like a great plan as it leaves you with only the Havoline so future oil change decisions are much simplified.
