Sorry to break it to you, but this is not a very good idea.
This idea is based on the fact that Conservatives don’t want to pay taxes for the things that Liberals pay taxes for. So what happens when some Conservatives don’t want to pay taxes for what other Conservatives want to pay taxes for? The same thing will happen and Conservatives will be divided into 2 more groups. This will keep going on and on until you have hundreds of groups with their own unique viewpoints.
You can’t generalize people into groups like Republican and Democrat. Each individual has their own specific needs and their own specific views, so no two Republicans or Democrats are the same. This means the best type of government is either an anarchy or a libertarian, in which people have the absolute freedom to make their own decisions and pay only for the things that they need.
