If you send it to a gunsmith that works with NO 1 rifles quite a bit, I'd bet it can be done. But probably less expensive to just sell the 45/70 and buy a 450/400.

That does complicate things a bit. I would think if the rim diameter is close to the same size, which I believe it is, you could make it work. Would probably have to adjust the headspace at the very minimum. Would be a matter of either setting the shoulder on the barrel back a bit, or facing off the chamber end of the barrel and deepenig the chamber and rim recess. Not sure how much that would cost?
