I armored umbilical part with external heavy plating. I guess they are going to be destroyable and untargetable subsystems in final version. I'm also going to bring back some signature features of original Icelus, like big, yellow lights [doctile4] on the rear engine sections.
As this is model from Shadow Genesis, it's gonna be released as soon as it's finished. No exclusives for SG: Reborn this time 
Great to hear it. I hope this kind of thing can become a bit of a trend, improving and fixing existing old tilemapped models this way without needing a complete rebuild.
For the Icelus, come to think of it, because of that umbilical, armored or not, I'd almost like a version of the ship that has it cut in two, so that if the subsystem representing the umbilical was destroyed one could FRED magic it into two seperate halves and float them away from eachother. Basically debris that still continues to function.
The front side would probably be unusable but the back could potentially still operate, perhaps as a "headless chicken". I assume it'd be a lot of work to do though so it's just an idea to throw out.
