HumbleP, you can order Flexicolor LORR developer from Vanbar, instead of tetenal kits, it is much cheaper whether one shot or replenished.

Also the recipe that's best considered online is likely this one

But the HAS level is much lower than Flexicolor let alone LORR/LU, meaning it's shelf life is probably shorter.

The shelf life of mixed LORR/LU is double of normal flexicolor, the difference is that it has more carbonate alkali, and double the amount of HAS as regular Flexicolor, while the same amount of CD-4. Not only is the shelf life twice as long, the replenishment rate is halved, meaning 2x as much film per litre.

I assumed it'd be too weak in the amounts used though. Eg, in the C-27 formula given in my link, it is 2g of HAS, in return, I assume you would use 850mg of the hydroxylamine chloride salt as a substitute, which would result in there being 920mg of KCl in solution per litre wouldn't there?
