No way--the internal volume is much too large for it to every play in tune. Single reed oboe mpcs are tiny. Think about a bari mpc on a soprano sax...

But I was thinking of decreasing the volume with cork until it came up to pitch.
I think you'll find a rather severe mismatch between the mass of the reed and the interior volume it's going to drive.

There are a couple of issues. Consider how stuffy and unresponsive single reed mpcs with extremely wide side rails are. Now consider the internal volume of an oboe reed--above the staple end. It's tiny. The oboe has an extremely narrow bore. You'd have to fill 75% of a sop sax mpc's internal volume to get into the ballpark. Where are you going to fill? You'd end up filling the baffle except for a narrow center channel. That means you only have something like 25% of the reed width actually being coupled with the pressure variations inside the mpc. The rest of that reed is nothing but excess baggage. It's going to be a nightmare.

Two more points: the mpc is much too long. That will screw with all the tube impedances peaks, especially all the higher ones. And then consider that the staple is analogous to the sax neck. You need it. Now look at the ID of the end of the staple and that of the sop sax mpc. That is the impedance mismatch from hell. I doubt if you could get a sound out of it, but I'd love to see somebody try just to see if I am right.

THe problem here is that the bocal of an oboe reed is not an equivalent length of conical air column to the neck of a sax, and in fact the necks of saxes vary between sizes in terms of the percentage of air column length they comprise.

What I remember reading is that the Runyon bassoon single reed MP used a clarinet reed, and that the tonal results were variably reported - I remember a range from "sounds almost exactly like a double reed" to "pretty awful".

What I remember reading about oboe is that someone made up a few single reeds for it using a special narrow reed (I'm guessing, cut down from a clarinet reed) but not much more than that.

My late friend Bob Kershner showed me a specimen of each back around 1990; but I've rarely seen or heard of them since.
Actually it appears that it is possible to construct a single-reed oboe mpc using a clarinet reed, as cited below in a research paper. The caveat is that the volume of the chamber has to closely match that of the missing conic apex of the oboe. A soprano sax mouthpiece has a much larger internal volume than an oboe reed. However it might well be possible to fill the interior of a nino mpc and create a throat that would match the diameter of the oboe reed staple, in such a way that a nino reed could be made to power an oboe. Failing that, a clarinet mpc would next best.

Thanks for sharing. It would be interesting to know how long it took Patrick to play the oboe with a single reed and if he had oboe experience beforehand. If you can play the instrument as a sax player without much practice it might be an interesting option if someone needs to double on an oboe. However, if you can actually play the oboe, I am not sure about the benefit of a single reed.

BTW, here is the direct link for the video, if anybody can't find it through Kymarto's duckduckgo link:
He is an oboe player. As an oboe player for many years, and a sax player as well, including sop and nino, I know the differences in feel between single and double reeds. They vibrate very differently. The single reed if flat and when it oscillates it does so in a planar manner. The double reed is curved, and oscillates by bending the reed inwards with the corners fixed and touching each other. IMO you can never get a really good clean oboe sound with a single reed because it responds very differently to changes in embouchure pressure. That is why, I guess, that the single reed mpc for oboe never really was successful.
