Or why not choose from among your alts in the Troops menu?
The main char can have access to INT/CHA based skills like trade (better prices at store) and Leadership. Leadership increases the number of alts you can have. The alts cannot generate, access INT/CHA based skills, or directly buy items. Essentially gold is pooled amongst all your chars (The property of your main char) and items are bought for your alts by your main char (Your main char buys an awlpike, now they and their alt-minions can equip awlpikes). The alts can possibly start and remain at a highish level (like 25).
Basically, it would be like building your own faction in Native multiplayer/having a mini-clan all to yourself. The less you devote your main char to INT/CHA based skills, the stronger they personally will be physically, BUT the tradeoff is less alts with more expensive equipment.
