I know this will likely be the type of reply you've asked not to read, however just to say this all the same.
Before going too far down this rabbit hole, I'd suggest pricing out all the materials - the wires, plugs, sockets and other consumables as you might be in for a rude surprise as to what it will actually cost. I can get these parts at trade pricing, for middle of the road to better quality parts and wires, I can't make one for less than I can buy one ready to fit.
Spider its not that I don't want to read it, I've read the numerous responses which ultimately follow a trend of "it will cost much more or you'll likely burn out here or set fire from here or it'll be a mess and time consiming". Its more I've already read them in all other similar posts.
I've already got a vague idea of what it will cost comparative to buying a new and if I replaced every wire and switch in the stock loom it would undoubtedly cost me more however I'm not builing all the components a standard loom has in it thanks to my cars previous owner whom removed components and/or changed cables for ones unsuitable and underrated for its application (think dual speaker wire in one connector from the coils to the ignition). Cost isn't my major concern, safety and knowledge is key for me and the current loom I wouldn't deem safe, nor the cost of a new loom necessary due to so much wasted wire and connections. So I'm going to embark on a hard lesson if I get it wrong but lucky to have the forum to help me understand or build on already asked questions
