When I have DOS binaries already, I would not recompile them for another processor type. Even for open source DOS binaries, I would be too lazy, given that you can run existing DOS and/or PC emulators on ARM-based operating systems which also emulate a classic x86 CPU. Note that DOS apps do not usually need much CPU speed, so the emulation speed loss is no big problem.

Of course you would save some energy by using apps compiled for native ARM, but then I would already have many native Linux or other apps for ARM in that case and again no need for a special DOS version running natively on ARM itself.

Of course tastes may differ and I remember that porting FreeDOS to other processors has already been a topic many years ago, so you can expect that your target audience does exist, but I myself do not expect it to be large.
