Tweeter as dust cover

[Bluecatman]

I’m currently working on making a diy homemade speaker driver, and I want to know if I can put my tweeter as the dust cover for it without the tweeter being affected by the magnetic field of the speaker driver

What do you mean exactly? Do you have a picture?

In general, loudspeakers are not affected significantly by the magnetic stray fields of other loudspeakers. Most of the flux remains withing the metal structure.

In the 1970ies Monacor sold a coaxial speaker that might have been what you meant. The tweeter was sitting on top of the woofer's inner pole peace. No dust cap was present. This speaker was called SP-125, iirc.
Foor nowadays, just have a look at some car audio speakers.
Best regards!

Fyi, they're assuming that you intend to attach the tweeter to the pole piece because if it's just glued to the front of the cone like a dust cap it will be flopping around as it's trying to play, causing doppler distortion (intermodulation distortion). This is not ideal, but to be honest might be the least of your problems. I'm sure you are aware, but while you might be able to produce sound, the challenges of making it sound like something you might want to listen to are immense. It's a little bit like trying to build a toaster and starting by mining the elements in the heating coil. Driver design is very complex. Not that you should let that stop you! Good luck.

Note how Philips mounted the tweeter in front of the woofer in their Motional Feedback speaker:
