Just an idea: just remove light lance, lance and heavy lance from the game. Put 3 different lances with the same length (180 length would be fair I think), but with different properties (speed, damage, etc). Not that it has to be only 3 lances, there can be more options. (Yeah I know there is double sided and great lance, I even use a great lance. But lancers mostly using those 3... ummm correction: only 1 of those. There should be more options for lancers.
Native lance system was mainly to restrict it via starting gold. In native, you have to make a choice to buy a shorter lance and but better equipment (mainly better horse), or a longer lance with worse equipment. Such restriction has no meaning in cRPG, since the amount of equipment at the start of a round is practically infinite.
