Robofrog evolution

With new patch, we can evolve frog to emperor frog with another 2 frog as materials. Why not evolve frog to robofrog with misterious frog, emperor frog, sphere frog as materials?

Because it would be the most OP thing in the game ?
A Robofrog is :
- up to 120 imps
- 18 burst frogs
- 1 sphere frog
- up to 20 "neutral elements" Cristals
So 1 burst emperor + 1 sphere frog + 1 mystery frog seems to be a price a bit unreasonable...

maybe different scales to obtain a robofrog
for example a frog that contains 50 imps of each imp frog
another frog that is 19 burst frogs:robofrog JR
1 sphere frog
and a King mermion who is 20 cristals in one unit
gather all to obtain a robofrog:
2 imps frog,one king mermion,1 sphere frog and one robofrog Jr
