Sac Chess still seems to be holding up well in practical testing on Game Courier, I'm happy to see.
A while back I toyed with the idea of making novel spinoff variant(s) that included the use of N+Guard+Bishop (technically NWB) compound pieces (I've called them Freemasons) and also what I've called Ships, that is N+Guard+Rook (technically NFR) compound pieces (using either an 8x10 or 12x12 board). I had, subsequent to inventing Sac Chess, had the feeling these two triple compound pieces perhaps ought to have been included in a Sac Chess-like game, somehow, as they perhaps logically complete the set of thematic compound pieces added to the standard FIDE piece types. On the other hand, there seems to be no precedent for the use of these triple compound piece types in previously fairly-widely played CVs, e.g. shogi includes the promoted B & R types, at least, while I recall Amazons had been fairly popular, in a variant of chess played in Russia long(?) ago - even centaurs have been employed (Courier-Spiel). So, I don't feel the urge to use the Freemason and Ship compounds as strongly as I once did, as I now see Sac Chess clearly uses the 'classic' compound pieces, as Carlos once put it.
A side issue arising from all this that occured to me is: what values should the Freemason and Ship piece types have? If we note that computer studies place Archbishops (let alone Chancellors) very close to a Q in value, and also place Amazon=Q+N in value (only), at least on 8x8, there doesn't seem much room to put Freemasons and Ships between Archbishops (or Chancellors) and Amazons on a numerical value scale, one might guess (at first thought anyway). I'm not sure what I'd speculate any future computer studies might (approximately) give for the values of Freemasons or Ships, but my own tentative valuation of an Amazon (as =Q+N+P) gives more room to fit Freemasons and Ships on a values scale (e.g. for armies on 8x8 or 10x10), at least. [edit: Fwiw, for 10x10 my own tentative estimates place Chancellor=N+R+P=3+5.5+1=9.5; Amazon=Q+N+P=10+3+1=14 and Ship=(N+F+P)+R+P=(3+0.75+1)+5.5+1=11.25, for example; if I only changed the value of an Amazon, to be equal to Q+N=10+3=13, then its value would seemingly be too close to that of a Ship's.]
