I agree with your point, but as I understand, at 'lower' speeds (the range of speeds that I am referring to), that is 1/400 or less, things are different. At such 'low' speeds you have most (if not all) the frame still not blocked by the first or second curtain, so you don't need any long pulse to illuminate the frame, at the contrary, a very short pulse can do it. For example, the AD200 at 1/128 power have a t0.1 of 1/11000, and the humble Metz 48 AF-1, at 1/128 have a pulse duration of 1/25000. But I can fill the frame at 1/200 and 1/250, and near full at 1/320 with AD200, Metz 48, V850, etc. at minimum power settings. You can get a thin dark band at the bottom, but the frame is still usable.
From my point of view, this is a way to 'stretch' your sync speed.
Practical applications may be debatable, but please take a look to this post of David Hobby: Strobist: SLC-2L-02: Two-Speedlight Daylight Group Shot. He is 'exceeding the sync' of his Fuji X100F camera, getting a small dark band at the bottom of the frame, to get an effect that he wants. I made my experiments after reading his post. Again, under my point of view, I'm doing exactly the same that David explains on his post (except for his nice picture), that is, 'exceeding the sync just a little', just for fun, that's all, to check that it was possible with my equipment.
Regards.

Ok, I'm auto-answering myself. Let's forget the above trick for now... I have read again the #1 post and the original question. If you want to control power for the V350P, as Class A pointed, you will not be able with a V6, you will only be able to trigger.
If your idea is to 'build' a Godox system, and use it as your main system, instead of another V6 II to control power for your V350P, you could get a cheap XT16 trigger and stack on top of the Cactus V6II, so you will be able to control your RF60 and also your V350P, maybe only for normal speeds.
Stacking a Godox trigger is a kind of 'quicksand terrain', depending on the firmware version you can get HSS sync or not for your Godox lights. But an XT16 is really cheap, and can give you more control over your V350P easily.
Regards.

Well, you can use some trick to sync at speeds up to 1/500 or so, without setting HSS or 1/1 power ;). Look at this post to 'view' what I'm talinkg about: Xpro-P TTL Wireless Flash Trigger for Pentax - Page 9 - PentaxForums.com
The idea is to use the POWER SYNC ADJUSTMENT of the V6II to wait a bit after the HSS signal has been triggered, this way you put your Godox flash (or other) on top of your V6II and you sync at speeds above normal sync speed. I have used this trick with a flash on top of the V6II (TX), a flash as slave on a V6 on RX mode or with a pair or trigger/receiver, the trigger stacked on top of the V6II and the flash on the receiver.
But for every flash or trigger you need a different adjustment, usually the range 23-27 is good for the flashes I have checked. For example, AD200 works with '24' but V850 needs '27'.
Also, you need an old firmware for your V6 II, 1.1.013, to make it work.
Regards.
[EDIT]
Sorry Class A, I see that you were talking about a V6 II in RX mode, and I was talking about a V6 II in TX mode, on the camera's hot shoe, so maybe my answer has no sense, my apologies. Anyway is a nice trick isnt' it :D ?
