Sorry, I'm not sure I fully understand your suggestion, however you are free to begin the polar-alignment routine pointing from anyway. If you wish to start 30º East of the meridian and then slew West 30º twice, you can. So, when you start up, slew the scope to wherever you want and begin. That said, if you are not pointing near the pole, you will very likely have major issues (your telescope bumping into your tripod/pier if you slew across the horizon by 60º). In fact, you should get a warning about that from the polar-alignment software. If you're pointing close to the pole, that is not an issue.

But what I wanted to say is that when the polar alignment starts pointing to the pole or near Polaris, the RA axis starts at 0° or 00:00, then moves to +30° or 02:00 and finally ends at +60° or 04:00. There is a lot of bending / flexing in that place and this negatively affects the alignment.
This can be avoided in a very simple way by starting at -30° or 22:00 and ending at +30° or 02:00. As you say it doesn't really matter where you start the procedure. But by default most telescopes start from their park position aimed to the pole or near Polaris.
It would therefore be useful to have the option to 'align symmetrically' or alternatively 'enter start position'. Then there is no need to manually go to another position at the start of the polar alignment.
And since everyone with a non-fixed setup has to polar align every time, that would be a welcome (and not that hard to code) feature.
If either are bending or flexing to a point where it's interfering with the polar alignment, I would recommend to worry about the pier construction or buy a more sturdy tripod. Before you worry about anything else software side.

- the entire setup is perfectly balanced
- the mount/pier is completely rigid
But even the most expensive mounts/piers never will be completely rigid and in addition a small imbalance is desired to improve the guiding, so that there is always a small force against the leading or trailing edge of the worm.
As long as worm gear mounts are used without spring pressure on the worm, probably the backlash as result of using symmetrical positions before & after the meridian, will make a greater contribution to the PAA inaccuracy than the flexing caused by the imbalance. And of course FL and the weight of the telescope will play a major role.
However, with spring loaded mounts there seems to be an advantage by using symmetrical positions before & after the meridian to polar align, no matter how small the flexing / bending may be.
I haven't had the chance to take measurements yet because of the bad weather, but I will soon...
