Inokatsu is simply an upgraded WA.
They are skrimishable, as long as you carry gas and enough mags to be effective.
Cost for a usable GBB would be the same as a PTW, but unless the U.S. allows them in, the technology isn't going to progress as fast as we'd hope. If companies can't sell them to the big US market, and they are limited to the dozen that will come to Canada and whatever the Asian countries use, it's not going to get a slough of aftermarket upgrades.
I wonder how long it will be before Canada follows the US in prohibiting these guns? All you need is a trigger group, bolt carrier assembly and barrel and you have a functional AR. How long it lasts though is debatable, but that's why the U.S. won't let them in.

Democracy is two wolves and a sheep discussing what's for dinner.
Freedom is the wolves limping away while the sheep reloads.
Never confuse freedom with democracy.
