I encourage you to read this forum in depth. Modders have been struggling for years with the issues you mention, and the RS2 team made their decisions after a great deal of consideration and testing.
Have you looked at the official submods for faster battles? You might also be interested in Granto's work, if you have a look at the submods forum.
The problem of cavalry costs, for example, is a very serious one, with no easy answers.
