I have a suggestion: serge where you can and sew where you must. That gets rid of the "meeting points," etc. problems. Also, I can choose the width of my serged seams on my Husky serger. Check and see if yours can do this too.
Thickness is an issue but, sometimes, so is time.
Note: my Elna still does most of the work around here.
Have a wonderful day --------- second day of spring.
