The tax thing could have gone on for a long while as a low level disobedience without exploding in revolution if the British government had reacted to events like the Boston Tea Party by investigating them as criminal activities and charging those responsible, rather than closing down the entire Port of Boston and abolishing the Massachussetts assembly.
An overall compromise would be something like:
- The colonies are allowed to trade with other colonies directly, if not with Europe
- An acceptance that sovereignty ultimately lies with parliament, but sovereignty will be devolved to the colonial legislatures for all domestic matters
- Religious establishment and practice in the colonies will always be considered a domestic matter
- The colonies will be expected to make a yearly contribution to imperial coffers, larger than present, to be raised however the local assembly sees fit
- The colonies will have representatives in the imperial parliament, and it is promised their views will be taken particularly seriously for matters that affect the colonies
- The colonies will not make war, either with the natives or with foreign powers, without acceptance from parliament
- Westward expansion will be allowed in an orderly and timely manner
- Commissions in the British armed forces will be made open to the colonists, particularly for those stationed in the Americas
- While parliament may decide where troops are based, the precise location and manner of their housing in the colonies will be decided by agreement between the local assembly and parliament, and paid for out of imperial coffers
- Each colony will establish its own court-martials for trials of soldiers accused of crimes within its territory
- The principles enshrined in the 1689 Bill of Rights apply to all citizens throughout the Empire
