I felt compelled to comment on this aspect. 
Honestly, the amount of customisation that takes place in Pakistan, and the ability of our people to deliver on such custom jobs, is quite unrivalled anywhere in the world. I've found that all you have to do is have a firm idea in your mind about what you want done, and be able to translate that idea to the comprehension of the fabricators and mechanics. All too often, we'll take a glossy photograph out of some magazine to the mechanic and say: "Ustad...bus aey cheez bana dey"...only to have him reply that he can't...or won't. At times, since this is something that falls outside his area of training and/or expertise, he ends up botching it, completely. Which sours the experience for all concerned. The car owner ends up deciding the Ustad lacks any capabilities...and the Ustad himself, vows to never attempt such a thing again.
I haven't seen very many attempts at channeling and body-dropping such a large-tall truck, and the people working on Sleipnir certainly had no idea about what I wanted, or how to actually go about it. Now, after doing it, it will hopefully become part of the collective experiences of at least one team...and this practical knowledge will be 'out there' for others to capitalise upon as well. Similarly, suspension-grafting. Now that we've seen it can be done quite easily, I'm sure there will be many more trucks with 'chimaera' suspension being attempted in future.
As car owners and enthusiasts, I think the onus rests on us, to not just dream wild but also provide our build teams with the practical knowledge, direction, and guidance to attempt such stuff. As for the execution, I believe our workforce is sufficiently talented to deliver the goods, every time.
