I just happened to be in the same predicament a month or so ago.
Here is what I did.........I dumped the idea of a "glove" and instead thought in terms of a couple pairs in layers.
First I bought thin silk gloves.........then on top of those I used a polypropylene glove liner (cheap), and then overtop these I used thinsulate lined deerskin gloves from the hardware store ($12.99)......which I waterproofed with mink oil.
I also tried GI issue wool liners, but the polypro outperformed them in an "ice water test"........where I logged the temp drop inside the glove from room temp to freezing with the glove(s) submerged in ice water.
The liner/liner/glove combo was great for hunting.......simple work tasks were manageable with all of them on. For fine work (loading/unloading gun, etc) I slipped the outer glove off.
