Will this mod decrease fuse rating?

Per experience with one premier audio designer and a team of designers including HP's former top trouble shooter (final diagnostician for the Pentium chip prior to release), it is difficult to overstate audio performance upgrade via mechanical damping (clear silicone sealant, epoxy, etc.) applied to caps, fuses, chassis, resistors, transistors, etc.   

I consider applying silicone around OEM Hypex Ncore fuse.  How likely would silicone trap heat, thus causing premature failure?

Well a fuse acts as a temperature sensing device.  As the current through the fuse increases, the fuse element gets hotter & hotter until it melts!  So thermal insulation will cause the fuse to trip at a lower level. So premature release yes, but it's not a failure.

Yes, I suppose the mod is the failure!

I suppose same outcome with plumber's tape wrapped around the fuse?  Guess I'll just try it and make sure I have spare fuses available.

It's probably why Audio Magic uses a polymer inside their Nano-Liquid fuses. You get your mechanical dampening w/o the overheating.  8)

I suggest you use so-called "ceramic" fuses, not conventional glass-tube fuses.  :)  Then you don't have to apply damping substance around the glass.
