Welcome John.
Several have tread the same path as you propose.
Very little new in speaker design for the past say 50 years, although Martin King has developed a MathCad application that can be applied to a variety of speaker types.
Drivers have improved marginally in that time.
Unfortunately most speakers have way too much invested in finishes.
I had Bob Brines (now retired in Arkansas) design and build my speakers. He is a gentleman, knowledgeable in MathCad, and charged very reasonable rates.
Take care and have fun.
