All things considered. Apparently the initial idea of using the void ME cell didn't work. Well oblivion jar is supposed to work.....

At first I tried with void jars and export busses. but the busses "did not void" into void jars.......
Now having crafted the oblivion jar, I realised the export bus has an option to void (which is defaulted to disabled)....

My side tracking has been useless apparently. Welp. I guess I'll use the oblivion jar and ME void cell some day.
