The draft specifically tells you not to do that:

"If the data is to be sent via some other transport, a transport encoding suitable for that transport should be used instead of Base45."

Base45 is mainly useful for binary information in QR codes.

I wish they would call it something like QR45 then, not Base45.

It’s a B2T encoding, not a qrcode mode (the mode is 2).
