So, I can make a small packet of Metol and let it be packet A, then everything else as packet B.

Would this work with THIS recipe?

Water at 50c 750ml
Metol 3g
Sodium Sulfite (anhydrous) 45g
Hydroquinone 12g
Sodium Carbonate (monohydrate) 80g / (anhydrous) 66.64g
Potassium Bromide 2g
Water to make 1000ml
