TheBrokenLance, the SLDF, as part of preparing for the Exodus, took complete copies of the schematics of all known, in use or proposed BattleMech designs including historical machines from the Age of War. For example the Kuritan Dragon specs were used to develop the Great Wyrm second - line machine. TRO 3060 has the details if you want to know more...
So, yeah. It is entirely possible. Interesting to see the similarities between the two Mechs in a side - by - side comparison too.
Thanks for the update. I'm grateful to both the in-universe and out-of-universe designers; the sleek torso reminiscent of a fighter jet fuselage is a sexy look, and it's cool to see on both historical and current designs. However, from an in-universe perspective resurrecting the
Hector was an interesting move from whatever Nova Cat 'mech designers produced the
Supernova. Unlike the
Dragon, which was brand new at the fall of the Star League and good enough to be a mainstay of the DCMS for centuries, the
Hector was comparatively ancient, disliked even in its own time, had exposed actuators, and went extinct by the end of the Age of War. Still, it's hard to argue with the results; the
Supernova is a beautiful machine, aesthetically, logistically, and in terms of battlefield performance.
