Your definition of 'likeness' is fine. Similar, or resemblence would be synonyms.
The issue is what is the word 'likeness' is referring to??
We know what the word 'image' is referring to. It is referring to the shape of God.
It is unlikely that the word 'likeness' is also referring to the shape of God, for it would be silly redundant. So the words 'after our likeness', has to be referring to something other than God's shape. LDS believe 'likness' is referring to His substance or what He is made of. Using the 2 synonyms, God's substance is similar to ours, or God's substance resembles our substance.
Putting the whole doctrine together this verse is telling us that God's image is similar to our shape, and God's substance is similar to our flesh and bone.
Since we are made in His image, after His likeness, it makes perfect sense, unless you believe God is a formless, immaterial Being, and then you would have to work extra innings to sidestep this very piculiar, very troubling verse.
The verse in not troubling at all!! You are making it in order to force it to say what you want it to say. Bottom line----likeness is not the same as the actual object. Reflection, image, resemblance, lookalike, You claim God could have breathed His substance into 'Adam, that obviously did not happen or every creature that draws breath would be made of His substance. Do you still maintain this is what happened or were you just grasping at straws???
Repetition and redundancy in the bible is rampant!!!

The fool hath said in his heart, [There is] no God.
They are corrupt, they have done abominable works, [there is] none that doeth good.
The LORD looked down from heaven upon the children of men, to see if there were any that did understand,
[and] seek God.
They are all gone aside, they are [all] together become filthy: [there is] none that doeth good, no, not one.
Have all the workers of iniquity no knowledge? who eat up my people [as] they eat bread, and call not upon the LORD.
There were they in great fear: for God [is] in the generation of the righteous.
Ye have shamed the counsel of the poor, because the LORD [is] his refuge.
Oh that the salvation of Israel [were come] out of Zion! when the LORD bringeth back the captivity of his people,
Jacob shall rejoice, [and] Israel shall be glad.

Corrupt are they, and have done abominable iniquity: [there is] none that doeth good.
God looked down from heaven upon the children of men, to see if there were [any] that did understand,
that did seek God.
Every one of them is gone back: they are altogether become filthy; [there is] none that doeth good, no, not one.
