I see.
Victor's 1812 cavalry presumably does not quite meet the criteria? Nafziger (812HAB) lists them as:
30th Brigade
Baden Hussars (400)
Saxon Cheveux-leger (550)
31th Brigade
Hessian Cheveux-leger (350)
Berg Cheveux-leger Lancer (700)
Which is unfortunately spread over 2 brigades, includes a non-CoR unit, and has no horse artillery.
A (non-AB) army based on Victor's corp would offer an interesting mix of troops since the OOB included French (Legere, Line and provisional troops), Berg, Baden, Hessian, Westphalian, Polish and Saxon infantry, with French, Baden, Berg and Polish artillery, and the cavalry above.
An AB-size force like this could be interesting:
Victor's 9th Corp (Empire)
28th Infantry Division (Attack +1, p109 subcommander rating)
5 Polish Infantry (Rel/Exp/2)
2 Saxon Infantry (Shaky/Exp/2)
1 Polish foot battery (3 Med Foot guns)
+2 Polish infantry
Organic Corp Cavalry (p120 other subcommander rating)
1 Berg Cheveux-leger Lancer (Rel/Exp/Pur/Lance/+)
1 Saxon Cheveux-leger (Val/Exp/Pur)
1 Hessian Cheveux-leger (Rel/Exp/Pur)
1 Baden Hussars (Rel/Exp/Pur)
