Well, I have already stated that house creation and management should (for my taste) be more detailed.
I've seen several threads of people posting their own house rules awaiting feedback and constructive criticism, so I will do so too.
I have uploaded 2 word files with my house rules.
The first has to do with house actions. I made the house action like the combat and intrigue rules. Houses now have several actions to choose from, with many of them promoting the conflicts between them. Each house has either two lesser or one greater house action. Houses can use reserve wealth or influence (like in Birthright using gold bars or regency) to lower difficulties for the checks, while rival ones can spend their reserve resources to make the tasks more difficult.

The second has to do with tweaking the house creation so that most of the resources to be spread out to individual domains making each of them separate realm entities.
Consequently the House Fortunes bonus/penalty derives from each domain. The magnitude depends of the domain's ratio population v law v land score in comparison to the domain actual population level.
Finally each domain provide an amount of temporary reserve wealth and influence (again this amount depends on the pop level and the above mentioned ratio). These temporary resources are not added in the resource score of the house rather they are only used to take costly house actions for the month they are collected.

Any feedback would be appreciated, especially regarding balancing issues that might be broken.
