Toilet fall… too steep!!

[Oscart]

Installing a new bathroom and moved the loo not all that far from original location. Basically just turned it round… the fall I calculate to be too steep.. help!
Loo states 185 soil centre plus 4 mm for tiles and 6mm for backer on the floor we are going to be up at195/200mm off the floor. I make the centr of my existing beach to be 140 off the floor at best. A 50mm difference and a short run of only 80cm max…. Any advice welcome

Is it directly behind pan, or to the side?
Is it plastic or cast iron?
They are thin tiles!!?

All plastic, two loos one coming from lhs and one rhs of stack (through wall) both offset by around 150/ 200 mm from stack

Oh sorry just re-read it, you have 80 cm ( 800mm) you’ll be fine just connect it all up.
I thought you had 80mm, that would have been more challenging
