Can I get by with replacing my lower control arms only?

[Bird]

I've been in the process of making my TJ more offroad capable, replacing various parts for stronger more durable parts.

Control arms are next and likely going with Savvy or Currie " Johnny joints ".

I'm having no issues with my current arms and would like to simplify this job by skipping the uppers.

Is this advisable?

Unless you need the adjustment out of the uppers to achieve a better pinion angle you should be fine.

Sure, you can but to take full advantage of adjustments best to have both. The stock arms are actually very durable and designed to twist, just fyi.
