Hi there, good to hear from you, and no worries, real life must come first.
A flight mechanics table that covers everything would be awesome, but I was warned by Orph that having too many ships in one table might make FSO crash and cry, so if that happens we would need to split it into several smaller ones - probably one for 'general' FS campaigns that would also include the smattering of non-standard models that those campaigns use; Vassago's Dirge, Uncharted territory etc., then one for BP, one for Shadow Genesis, one for Exile, one for Just Another Day etc. I'm already starting on doing this for Reunion and it seems to be working well so far.
As for the cockpit mods. The Herc 2 looked ok until I looked backwards, then it looked kinda goofy. I think what I was seeing was the engine exhaust grills 'through' the rest of the ship, but it lacked a sense of depth so it is hard to be sure. The Ulysses honestly looked terrible from every viewing angle, due, I suspect, to the relatively lower polly model it uses. This would presumably be a problem for other lower polly ship models too, of which there are still quite a few kicking around in various campaigns.
A minimalist generic cockpit might be a better way to go and definitely much easier. The poster of this video basically ported the Viper cockpit from Diaspora (BSG) which seems to work well enough without being obtrusive. I have asked him how he did it and I'm waiting to hear back (true at the time of writing)
https://youtu.be/puU3ugrleWoTBH, I'm going off cockpit mods and I'm beginning to think that FSO simply isn't set up to do them properly, since they always seem to have major issues.
The updated flight mechanics, however, are an absolute godsend and make a tangible improvement to gameplay. So far I have only really used glide and reverse thrust, but even these have made FS far more enjoyable by eliminating some of the biggest bugbears I had with FS since the first FS came out in '98. Thank you

I'm more than happy to keep helping you this so let me know if there is anything I can do

All the best,
Iain
