Here's the challenge, have the Volga Bulgars do better and expand successfully at the expense of the Khazars and Rus states in the early medieval period, with them dominating a realm, at least until the arrival of the Mongols, that goes at least as far west as the Dnieper (but the further west the better, so if it goes far enough west to border Poland, Hungary, and the other, Balkan Bulgaria, or the Dniester, even better) the northern Caucasus, the northern Black Sea coast, and touches the White Sea and Baltic Sea.
