As enlargement of pinion depends on offset I expected it to be a huge one, but this is not the case. The directions you have described work for pinion enlarging, but at this ratio the diameter of pinion certainly won't get bigger than of the gear. There is no ratio limit to hypoid method, 1:1 sets are also possible: "For power drives, the ratio in bevel and hypoid gears may be as low as 1, but should not exceed approximately 10." - ISO 23509

It might be helpful to read the ISO 23509 standard - Bevel and hypoid gear geometry. It describes 3 methods of calculating the hypoid gear geometry, formulas as well as example calculations. These 3 methods can also be found in: Bevel Gear: Fundamentals and Applications, Klingelnberg J., Springer 2016.

Hope it helps.
