These Oxy plates work fine with the DH regulator:

I rather like them with several caveats, the shoulder straps tend to sag making entry and exit somewhat more difficult than a hard plate and the plate is flexible and therefore negative tanks will tend to flop side to side. This is expected since the Oxy plate was intended for aluminum 63/80 cylinders and is fine with the steel LP72 also. I chock my tanks by installing a cam band pouch left on the top and right on the bottom and tucking them in close to the plate to help prevent the tank from rolling. The wing will sit partially obscuring the dh cans. It is possible to get the tank and regulator lower and more centered between the shoulders with the Oxy plate than with the VDH plate, maybe
.
As to the OPs question, install the wing to the VDH plate, especially since you have the larger 30# wing, such that it is as low on the plate as you can. The upper fabric will sit between the regulator cans and the cylinder. Yes it will be pinched and in use it will not matter. And if you are well trimmed and horizontal in the water the air will move the full 360 degrees. And of course, if weighted optimally, there will be minimal air in the wing, only enough to offset the cylinders negative buoyancy. Push the plate and wing up when installing to the cylinder such that the cutout in the plate is about .5 inch below the bottom of the can. This helps with optimal positioning and prevents the wing from trying to extrude.
And you will note here, though I have a dastardly single hose regulator installed, that on my VDH plate with the 23# VDH wing installed the top of the wing is below or even to the cutout:
Yeah, sometimes I feel like getting a full breath of (dry) air, spear me.
