So ... Paul was on the GB, eh? From a brief consideration of Galatians 1-3 it seems to me that he wasn't aware of that fact. He was oblivious to that fact, the way the text reads.
One thing is certain, he didn't attend weekly meetings with the GB. Nor did he have any hand in the content of the semi-monthly publications that were being distributed by the First Century disciples in lieu of teaching.

This precise premise featured a confront of sorts between my two CO teachers at Pioneer school a few years back.
The CO taking the 'teaching' slot for the session, whilst the other sat in the group, stated that Paul was not on the GB. The other CO 'corrected' him, not with scripture, but with line item refs to a Watchtower volume of the past that 'proved' he was.
During the 'intermission' they both adjorned to the KH lib to seek the catachismic proof offered. When the session resumed the offending CO offered a brief apology for having mistated. Now we were all on the same page, and I imagine that all those who remain in the 'truth' from the group are convinced of Paul's postion - not by having been eyewitness to the 'proofs' , but by having been eyewitness to these two CO's confirming it in the Wt. I never saw either of them confirm it by scripture.
