If you go the diversity route you get to experience both sizes and formulate your own beliefs.
With diversity comes complexity.
If you want a generator hub you have to choose between wheel sizes. You need different replacement tubes. You can't swap wheels from one bike to the next.
All food for thought.

27" tires: what good ones are there in the 28 to 32 mm width? I am debating whether it's worth building a new set of 700C wheels for the trike or whether simply to replace the aging IRC 27 X1 1/8" tires. I want light, fast road tires. Any ideas, class?
Riv content: I've moved from 559 X 23 mm to 559 X 32 mm on my Riv commuter.
BTW: here is why you need a trike to carry loads. Not mine; from Trikes and Odd Bikes blog. <image.png>
I think your best bet is the 27 x 1 1/4" Pasela.
Here's my 60 cm MAP Randonneur:

I think it looks just fine w/650B wheels. And note those wonderful red
Hetre tires: nothing even remotely like 'em in 622.
OTOH, if there were a selection of top quality tires available in 630mm, that too would be a reason to stay with the existing size.
But for a long term investment, given that an investment has to be made, and, #2, given that there is only decent 630 tire and that even this may not be available forever, I expect that it would be prudent to switch to 700C. Right?

Assuming your brakes can accommodate the smaller wheel size, then
unquestionably the answer is yes. There are no tires in 630 to equal
the likes of the Grand Bois Cypres available today. The Pasela isn't
bad, but it's not "first chair quality."
While I'm sure somewhere in a parallel universe there are 650b
studdies, I have never seen them, and I sure as shoot wouldn't have
been able to order them from Amazon for a song, as I did.

Actually, studded 650B snow tires are available in this universe. Peter

I'm not sure there are any studded snow tires, 622 or any other size,
available "for a song."
No 650Bs, though.

I just built a 700c dynamo wheel I can theoretically move between 4
household bikes (two have dynamos already). The one I want to use it
on... well, I should have used a much wider rim.

If it were simply a matter of replacing the existing tires, I'd probably just use 630mm Paselas.

You could use a puffier tire in front to keep everything level. Kind of weird, sure, but not as weird
as having a trike. :^)

In which case I doubt you will ever make the conversion.
