Is it permissible to distribute profits to some heirs working in the company, but not to others, given that the general profits revert to the company's capital?

The money mentioned is an inheritance for all heirs, and each heir has their legally stipulated share. Any heir has the right to demand their share, and their request must be fulfilled and their right expedited. If there is a minor among the heirs, their guardian or trustee shall manage their money for their benefit. If all heirs agree to maintain the current arrangement of your work with the inheritance in exchange for a fixed salary and a share of the profit, there is no harm. Otherwise, it should be according to what everyone agrees upon. You are not permitted to decide anything regarding the inheritance without the consent of the other heirs. In matters related to the rights of minors, reference should be made to the Sharia courts.
