It is true that shorthaul agreed to do regional flying for less money, and inferior conditions to longhaul FA's. But, the conditions and pay that the 'new hire' longhaul FA's will work under (should the EBA be voted up) are substantially lower than shorthaul.
Do you really think these crew members will be happy to work alongside you, when you work less hours per roster, and get paid a sh*tload more? Maybe they will be happy enough for the first few months, but when the novelty wears off, and they are exhausted and broke, what will happen then.
What kind of a workplace environment will it be in 5 or 10 years? Will you still be around then?
