It’s is an advise for some guys here only! It’s not about your excellent character customization system, @ OK! 
The advise! it`s not mine!!! Several professionals have told me it in the past.
Does not sound very cool to reuse heroic characters models developed for other projects in an authoring project, even though these characters are free to be reused. If are character with heroic and peculiar appearance they will always compromise the overall works quality. Reason why is very important the Concept Art stage, so that a job can be considered a finished product when it is released. Not another mixed or patched work. By reusing things not authored by you, and the same things seems in different projects used by different authors, no matter how good is your work at all, The great public does not forgive, and has a good perception about it, and Will consider your work amateur, again, no matter how good is your work.
In this way I am more interested in logic, i.e, In logic, a customizable playable character for testing, good logical solution for skeletal controls in the animation blueprint, good UMG integration example, and one generic not heroic model template compatible with Unreal skeleton as one plug-and-play example for including authoring characters.
At this point lies the great question. Which will be the focus of the final product: The character customization system will be a ART product or blueprint programming?
I think to arrive at a fair value is interesting to think of the following way:
Let’s suppose if you were hired by one indie company as freelance artist or programmer, how much it costs in money the hour of your work and how many hours were spent programming and developing it? What is your sales expectation (how many units do you expect to sell). The marketplace’s percentage… Does not needs to answering it, it’s not a question.OK.
Is the expected sales number, which will tell you the final fair value, which should be similar with how much you think is worth your work in the hypothetical indie company. But more one advise, Sorry, expected sales is like a game, you can achieve your goals, and depends on interesting price and demand. What is the expected demand, you have a pool on your thread? Do you think you will sell 10, 100 or Thousand! The sum of all sales will be equal to how much your work worth, or will it be much more than your expectations?

LODs are not problems, it are easily extracted from the original high poly skeletal mesh. And does not are distinct characters.
