If you're hell bent on the Orange, I'd say just save up for that and stop worrying about the warmth until then. You'll have more warmth than you know what to do with at that point
If you really need it now, most pedals that will warm your signal without turning it to mush should do the same for your rig. Emphasis on 'most' and 'should'. Your MB is small enough that you should be able to drag it down to a shop and see if those pedals enhance or detract from the tone you're hunting.
Good Luck to ya.
