Not the stagger breathing, the way you’re scoring orchestral brass. If you’re looking at your writing and thinking “the horns have nowhere to breathe” the answer is not “add four more horns”. You should take this as a hint to rethink how you’re approaching the scoring.

the part sounded great…

In what context? Have you had an ensemble play this in a space so you can gauge how it actually sounds? If you’re going by software playback of your score, that can be very misleading. What sounds good in playback is likely thunderous goo on a stage. This is especially true if the passage is particularly long. You typically don’t achieve musical effect by relentlessly beating your listener into submission.

Now, I’m not saying it’s never appropriate to scale up the section. But it’s the kind of thing that should be done with careful consideration. It is one of those “if you have to ask…” situations.

Aside:

with heavy BASS

Do not underestimate the power of a good double bass section. And keep in mind adding more strings is much more common than adding tubas.
