That's incorrect. Obito did it all the time and we all know that he doesn't have that level of chakra. The amount of chakra expensed depends on the technique and how far away the dimension is, which is why it took Obito more to travel to Kaguya's vast dimensions. Amenominaka, Kaguya's technique, is different than Kamui and Amenotejikara, requiring about the chakra of a full tailed beast in order to use. Amenotejikara however (as far as I know) has not been stated to be specifically chakra taxing, but merely drains Sasuke's ocular power.
I agree that Sasuke has the chakra to manifest two Perfect Susano'o at the same time, but Amenotejikara does not take that much chakra.
