I am roughing-in a shower. I have 1/2" pex to the diverter. If I put
a large pipe on the riser (diverter to shower head, that is) is that a
problem? I was planning on putting in 3/4 copper on the riser from
the diverter.

Thanks,

Use what fits. Won't be a hindrance, won't be an advantage. The shower
head is the controlling factor.

1/2 is good enough,no harm from 3/4 if that's what you have. I bet the
shower valve is fitted for 1/2

The diverter up to the shower is female 3/4 NPT. So, I could put in a
converter to 3/4 copper or 1/2 copper. Does it matter which one I
do?

A larger pipe from valve to shower head will very marginally increase
the time it takes to change water temperature.

Why 3/4"? I just plumbed my shower with PEX & used 1/2" PEX valve
to shower head.....seems to work fine.

New shower heads & valves tend to have some sort of flow limiting
features so you really don't need a large pipe to service the flow.

My opinion...in this case smaller is better......shower head is most
likely the limiter.

3/4" will make adjusting the temp slower. You will have to wait longer for each
change to reach the shower head.

Yup, a little slower.....about a second or so depending on
instantaneous shower head flow rate.

Since "low flow" shower heads are almost standard these days......
