Jenny Czech vs Amrita is doable, very very difficult but doable.
Yes, Would be very hard to pull that match off. Amrita does very few real competitive matches and in her last one Vs Antscha she lost badly and might not do another real match again
Jenny doesn't like to lose so only shoots Vs fighters she think can beat with no issues. Amrita knows many holds and might take Jenny in a match so Jenny might not want to shoot Vs Amrita.
If enough money is thrown at the 2 girls, might get them too agree to a match if both thinks they for sure is the best fighter. Would be very interesting to see who would come out of the match on top. I think they make for a good close match-up, so would help sponsor the match if it can be booked!!!
