Two thoughts knowing how these are being released:
1: I wonder what kind of numbers they'd do if they released an army builder with just like, four random round table knights on the same body with a tabards or something. Save the ones to put exta work into (or at least do new paint apps) for the big names like Gawain, Lancelot, Modred, etc. but just throw Bors, Kay, Gaheris, Constantine, just known but less famous knights into an army builder and make it relatively easy to do.
2: I can't help but imagine them getting the boredom bug mid-theme like they did with the Christmas Carol and chasing another concept after the first three or four figures.
