How would you make a mold of this?

It is a 'pod' that holds 2 90mm hella lights and a turn signal. current one is painted fiberglass. heavily built and I want a light carbon one showing the twill... my unanswered questions so far
- It has negative features because of the headlight tubes requiring a two part or more mold, or what I'm testing now, shore 60A for the headlight tubes and one piece fiberglass for the rest. or shore 60A silicone for the whole part with fiber backing for reinforcement?
- how to get a consistent weave pattern where the tubes transition to the overall body of the part. either have the same fabric piece lay into the tubes and have seams hopefully hidden? or have seams where the tubes join the main body of the part?
- infusion is the method i am gonna try to use. where should the resin feed line(s) and vacuum line(s) be located?

That looks amazing. One question I have is when you made the silicon bag did you use anything like sheet wax to account for the laminate thickness as your bag will be made to the mould size causing it to pinch some of the material.
This could account for some of the issues on the radii
