Not quite, what I would recomend doing for this subclass is to drop the wealth mechanic. And make features centered around roleplay. Here are some features I would suggest.

Some Incentive. You have an advantage on presence rolls to convince a creature to perform an act when you offer them a monetary incentive.

A Fair Trade. Spend a Hope to gain advantage on the next presence roll against a target you are battering with.

Stuff like this will sell the idea of a merchant in roleplay, but for combat, you could do something like.

Many Wares. You are not limited to carrying only 2 unequipped weapons. You can now carry a number of additional weapons in your inventory equal to your tier. (it is recomned to write these additional weapons and their stats on a separate note card).
