I sent you an email about ten days ago answering some of your questions - I mentioned agricultural contractors, vernalisation, yellow rattle.
.
In addition to what I said there -
I spoke with an organic farmer today - he cuts his docks regularly and sheep grazing helps.
My meadow has regenerated well without yellow rattle. Yellow rattle speeds up the process.
I wouldn't worry about the topping of yellow rattle over much. The point surely, is that the rattle as it grows, parasitises the grasses (and some other plants) weakening them and eventually creating small bare patches. So the rattle will have the desired effect during its growing season from March to whenever you top, or until it seeds, whichever is the sooner; the fact that you may have to reseed the rattle in the autumn, because the topping took place before seeding, is secondary.
I've been told by a well qualified and experienced farmer friend that knapweed heats up hay. That might rule out the normal seed mixes, though you can buy individual species. I suggest you ask your local farm sales outlet or a neighbouring farmer for further advice. Perhaps someone here will comment further.

What’s your soil and the land characteristics? She warns you may have to cut for 5 years if your soil is rich in nitrogen and phosphates, before even thinking about wild flowers..
In the para
If the grassland hasn’t been grazed or mown, or is tussocky, weedy or is becoming invaded by bramble or bracken: she recommends herbicide.
Hannah, if your organic efforts so far aren't working, and you choose not to use strong herbicide, then may be you will have to resign yourself to years of regular cutting, - forget the hay and introducing any flowers for a few years, as you would be better cutting those weeds really short every month, and, after all that, only once the weeds have gone, only then think about hay and a slow natural regeneration of wild flowers.
If the cutting would be too much to be managed with a scythe, then perhaps invest in your own tractor and topper/flail mower collector or use the services of an agricultural contractor.
The only sure way to remove docks which I've found is to hand dig the whole of the root ball in the wet season, so the roots don't snap. Yes, it's pretty grim. Spraying can sometimes kill, often it kills some of the root,and the remainder regenerates the next year, so when you dig it up, you can find half the root blackened, and half live. Digging doesn't work on creeping thistle - see the refs below.
The only alternative to herbicide, digging or cutting, I can think of, is covering the worst areas with light-excluding black plastic, silage wrap, for a couple of years, if you have the space to exclude the horses, but you would still have the weed seed reservoir in the soil.
I think it could be a waste of time and money reseeding before you get rid of the weeds.
If you reseed at any stage by harrowing or opening the sward up in some other way, you will be disturbing the soil and allowing light to it, and your weed seeds will germinate and you might be back to square one.. You'd be far better off not disturbing the soil, and allowing natural regeneration.
I accept that your horses will disturb the soil, so do all you can to minimise this, keep them unshod when this fits with their use, keep your stocking level low, and keep them away from the wet areas. The only seeding I do suggest, as I said in my email, is that you put sweet vernal grass or some other fine grass seed on the bare earth disturbed by the horses, so that desirable seed might beat the weeds' seeds in the germination race.
Yarrow, knapweed, and short plants such as celandine, speedwell, alchemilla, lesser stichwort, bugle and betony will probably naturally colonise early if they are not already there. They will survive cutting. They just won't flower whilst you are cutting. They will bulk up and spread vegetatively. When eventually you do cease regular cutting, you will be very pleased by the flowers that appear.
