if you are committed to using what you have on hand then you are either going to run into the issue of repeating base colour and or repeating spot pattern. Depending on one's level of OCD it will either be a problem or it won't.
Ultimately its your set so you do what works for you.
My own personal preference would be to avoid using a repeating base colour and spot pattern as well as any chip used in another set I already have so as to give the new set its own uniqueness.
Good luck with the build!
