Difference between "to do as much for you as" and "to do for you as much as"

In Cambridge Advanced Learner's Dictionary 3rd ed., one of the usage examples given for the entry much is:

One day I hope I'll be able to do as much for you as you've done for me.

Is the meaning still the same if I move the prepositional phrase for you just before the expression as much as?

One day I hope I'll be able to do for you as much as you've done for me.

They both have the same meaning. Let's simplify by replacing the noun phrase with a noun, and trimming away some of the clauses of the sentence.

I will do a favour for you.

I will do for you a favour.

Both of those are grammatically valid, and have the same meaning. The first sounds more natural, and is what most native speakers would say. The second is a valid form that you might find in a poem, folk song, old writing, or someone deliberately speaking/writing in that manner.

Both seem to convey the same meaning. However, the first one is more emphatic.It sounds best when "as much" is stressed.
