I know this isn't the answer to what you're asking, but I seriously believe what you're looking for may be based at least somewhat on misinformation and misunderstanding.
What I'm saying is there is a good reason why so many quality scope manufacturers are not offering low-magnification scopes with larger (than needed) objectives. The reason is that larger objectives are simply not needed above certain thresholds with each level of magnification.
Without getting highly technical, and assuming at least decent quality optics, an objective larger than 20mm will not allow any more useful light (to human eyes) than a 35mm objective at a magnification of around 3x to 4x.
I currently own some decent quality scopes with 20mm objectives.
In dark woods, I can clearly see deer before and after legal shooting times, with these scopes set on 4x. If I had younger eyes, maybe 5x.
If you're mainly using your scope set on 2x, it is just mostly unnecessary to have an objective larger than 20mm. It serves you no value, and is even a liability.
If I were looking to add a new low-magnification scope,
below is what highly appeals to me, and
there is good reason why this quality scope is manufactured with only a 20mm objective --- anything larger becomes a liability.

Lastly, as hunters, we have somewhat been "sold a bill of goods" with the mass marketing of both higher than needed magnifications, as well as higher than needed objective lens. I'm positive one BSK understands this with the higher magnifications, but same applies with the larger objective lens. However, to some degree, larger objectives may have more merit with lower quality glass.
