That would rather have missed the point of having a particle tuned to within a gnats-cock to make the experiment work as it is.
Sure. A 'full' direct measurement setup would require the clocks to both be at different elevations above ground level, with somehow a detector at ground level miraculously aligned to record (or not) arrival of each individually timed muon.
Clearly can't be done in practice. And even then, there is necessarily that complication of continual atmospheric momentum loss that can only be reasonably modeled as approximation.
So the cosmic ray generated muon experiment is inherently imprecise but good enough to establish SR time dilation works as advertised.
