he clearly equated FW with the Great Elector here - would FW have felt insulted by that?*
This I very much doubt. The Great Elector in 1730 was the only Hohenzollern to have been titled "Great" (and by his contemporaries, no less). He won some legendary military victories (Fehrbelln, aka the "In den Staub mit allen Feinden Brandenburgs!" one Kleist used in his Prinz Friedrich von Homburg play), was regarded as a charitable protector of the Protestant Faith, too, due to immediately after Louis had revoked the Edict of Nantes releasing his own Edict of Potsdam with which he invited the Huguenot into Prussia, and was respected even by Catholic monarchs (including Louis). Basically, I would be very much surprised if FW didn't see his grandfather as a hero to emulate. (He didn't have any personal memories of him, of course.)
(I also recall Fritz once made a sarcastic remark about the longest surviving of the Schwedt sons always saying "I'm the son of the Great Elector", which would not work if the Great Elector in the FW era hadn't been upheld as the greatest Hohenzollern of them all to all and sunder.)
