Implications of hacking Assembly Items for Shopify variants

I have a situation where Assembly items are being wrongly used instead of Kits. The best I can work out so far is that this was to support variants in shopify via a Celigo sync.

So for example, we have "Starter Kit" and this is an Assembly item. But it isn't "built", all the parts are always separate, and are picked separately. So when I read the NetSuite documentation, everything says it should be a Kit.

And the problem I'm facing is that NetSuite doesn't like to show the BOM (if that's the correct term) of Assembly items. One issue is we can't count inventory unless we "unbuild" these assembly items - in physical reality nothing is unbuilt.

We just started picking in-house, and I've been asked to show these Assembly components on NetSuites pick list. After researching, I realised that the NetSuite is correct - they shouldn't show, and I'm resisting hacking the template. (If you've worked with the template you'll it's not just a logical decision switch that hides the items, netsuite prepares a flat list of items which includes Kit components and excludes Assembly BOM items.)

I'm now trying to work out how bad the situation is. Is there an alternative that is equally as bad. I'm trying to find some blog posts about this, rather than the Celigo posts which tend to just be instructional about how to do it.
