Are there better or equal drop-in/no mod replacements for an 066 tweeter?

Working on restoring a 4313b pair. I asked this question in another thread in a round about way, but it wasn't the subject of the thread. Thought I'd try it as the subject. I did see replies suggesting a larger hole via hole saw and router, but id rather not modify the cabinet. Is there a drop-in replacement for an 066 that is sonically equivalent or better? Thanks.

If you're restoring a 4313B, you need an 066. They can be found.

I don't know of any 'drop-in' tweeters... one that would match the diameter,
mounting hole pattern, and response/sensitivity.

Figuring out how to install something from the 044 series or 035, 052 series would
be both more effort and not match: potentially requiring some crossover work as well
as changing the speaker, visually... but may sound better to you.

Thanks. Didn't even consider there would be a crossover difference. These 066's don't sound bad to my ear, but I am about to open them up to straighten the domes. If something happens or I decide I want to replace them, I'll be looking for original 066's. On another subject, is there a good way to isolate the LE5-9's to see what one sounds like compared to another? I saw in another thread that there is a difference in load on the crossovers if you disconnect the other components. Another tangent, but I'm learning.

bah. If you're curious, just hook them up straight and don't crank the bass or volume.
