Greetings lovely period property people!
Long time lurker first time poster here - currently trying to unbodge a west somerset 17th century sandstone rubble cottage with an 18th century extension and various 19th century+ retrofits!
The short version of this issue
I played the floor lottery and found quarry tiles - hooray!
There is a large section where there are no tiles. There was only concrete there which has been dug up and replaced with lime, leaving space to put new tiles on to complete the floor.
I cannot find a good tile match at reclamation yards or modern reproductions to complete the floor. I'm finding it very hard to find anything that is the correct colour, smoothness, size and thickness (they are 12" square, 1.5" thick, very smooth and orange but look red when dirty)
How fussy would you be about finding a good match?
And what would you put there if you couldn't find a match?
Possible solutions that have crossed my mind so far:
1. Putting down smaller quarries with a border - this won't work because the existing tile pattern doesn't leave a straight enough line for a border, and I doubt it would be very smart to try and cut the existing tiles into a straight line!
2. Putting down 6" quarries (using 4 to make a 12" square and continue the existing pattern kind of) - could work but I'd need about 280 tiles (based off calculation of needing around 70 12" tiles) and they'd still need to be the correct thickness, colour etc.
3. Just keep struggling to find an actual 12" match
4. Some other completely different thing?
Pic of my limecrete hole below:

Some additional details
I have had limecrete put down, but the levels are only just under where the existing tiles are (and nothing is level anyway because old house), so it's been suggested to me that I need tiles around 3cm thick instead to leave room for whatever ends up being used as adhesive.
I've so far tried:
Reclamation yards - none have even close to the number I need of 12" tiles in stock, many not in good enough condition for internal flooring anyway
Modern reproduction quarries (too thin so far, but good colour and smoothness)
Modern reproduction pamments (correct thickness and size, but can't find a good colour/surface smoothness match)
I have even got myself into a hole wondering if I can sand, stain, wax or linseed modern pamments or terracotta tiles to get them to have a similar finish (so many rabbit holes and I know nothing about tiles so most likely futile)
Bonus issue (in case the first one wasn't enough)
I also have this very annoying area near the front door which also needs replacement tiles. Essentially there was a concrete L shape where previously somebody had obviously put in a porch wall that was then removed before my time. The concrete has been dug up and lime put in its place. In addition, tiles immediately by the door are all smashed to bits and need replacing. Sorry for terrible pic, it's all I have right now as not living there yet:

I am 100% overthinking this at the moment, to the point that I may turn into a tile myself if I don't make a decision soon, so I would greatly appreciate thoughts from people who are more sensible than me (which is pretty much anyone)
P.S. if anyone has a patchwork type floor with different types of tiles/bricks/etc. going on, please do share pics, would love some inspiration to help alleviate this odd perfectionism I seem to be experiencing!
Thanks in advance!
