You can do that, but you need to use the exact same debian/changelog. Otherwise your SOURCE_DATE_EPOCH will differ and that'll likely change the binary. Cross building will not help you, because the cross toolchain presently imposes build-id differences. You may use a porterbox to build the package twice (with and without the patch but without changing d/changelog). Alternatively, debusine.debian.net (I'm being compensated for working on that) also has native arm builders and you might upload packages there for comparison.
I have both native amd64 and arm64 hosts available, but I thought of using a porterbox.
