“And once again, into battle!”

Guys. We held a tournament within our clan where players played with custom-made heroes. Each player chose the build, race, etc., for a certain number of points (race, spells, artifacts, skills and abilities; good skills cost more if possible). First, weaker players created heroes, then stronger ones, trying to avoid repeating races, skills, abilities, standard specializations, etc. So, the weaker players had some advantage (or whoever submitted their hero first :). The game was played on IRMG. To avoid playing the same thing for too long, each game was elimination-style.
I have an even better idea. After each match, a player takes the loser's hero (like taking a car after a race) and can play with any hero from the collection of stolen or original heroes in subsequent matches.
It is technically feasible; it would be very easy to create a mod that adds this functionality to the standard game (it used to be slightly more complicated).
Just throwing out an idea. It’s up to you to decide.
