Order domain cleric + diviner wizard = Mystic Theurge?

[Particle_Man]

A bit of a kludge, but the Order domain from Unearthed Arcana allows one, after 6th level, when casting a 2nd or higher enchantment spell, to get a lower level spell slot back (max. 5th spell slot back). This is very similar to the Expert Divination's Wizard ability to get spell slots back when casting divination spells of 2nd or higher level.

So would a cleric of order 6/diviner wizard 6 be effectively a mystic theurge, with a huge number of spell slots coming back to them?

Also, would the character get spell slots back if they cast 2nd level or higher cleric divination spells or wizard enchantment spells?

I'm not sure about Order domain's feature, but Divination Wizard's Expert Divination says "a divination spell of 2nd level or higher using a spell slot", not specifying Wizard spell, so it would work with Cleric spells. If the Order domain uses the same wording, then it would work with Wizard enchantment spells.
