Four foot X-wing (ILM tribute)

[427 Cobra]

I'm already about done with most of it, but I had to start on parts for the wings that are multiples, so I can finish them since they're the first things I made for this kit. I need some input, as I'm at a crossroads in the wing design. Below is a picture of the inner wing. I need to figure out how to make this so I can copy the construction without the casting process being compromised.

I'm thinking about making the wing sections solid, then drilling a hole in the master where this should be and filling it with wood filler to make an indent on the inside edge for modelers to lay a ruler between the two for marking, to facilitate drilling a small hole for a spar (red arrows) to go into the engine bay. This would allow for it to be more accurate with out the wings being hollow. I've even been thinking about leaving a slight lip around the holes for the inner wing details for those who want to make theirs look like the wings are hollow instead of cast . This way, the wing can be cast without ruining the mould with severe undercuts, and still look hollow for the most part. I'm also thinking about leaving the engine risers/bays separate from the wings, so they can be cast easier - and so that a modeler can discard, or copy the wings for those who would rather make their own hollow versions for studio accuracy. I'd make a small mark on the wing for this, so it can be placed correctly. Does this make sense?
