No. Night fighting is not the same as just flying a plane at night. Most "night fighters" in real life can only catch bombers if the NF is running full power and the bomber is cruising. On top of that the entire mechanic of night fighting, from taking off, navigating in pitch black, following radio leads and contacts you can't see ("take course xxx here, 10 miles out", and "visual range," and "he's behind you now" etc) it's not even remotely comparable to flying AH at "night"
And there's no point in having an arena. Only people flying at night are the ones that don't want to be engaged. HT said most of the server logged off every time the server cycled to "night time" so they removed it. They have the actual logs and know what was happening. They made the right choice.
How would flying at night be "not engaged"? It appears to me to be merely a different type of engagement.
I also think the WWI arena could/would be a hell of a lot of fun if it were developed.
I also take Gyrene's points as credible. The lighting issue is criitical. Night time ISN'T always pitch black. Consider this example account of a visual kill at night:

Occasionally success alleviated the boredom. Ground control radar vectored the 6th Squadron’s “Bluegrass 56” over Saipan for five minutes, until R/O Flight Officer Raymond P. Mooney picked up the bogey on his airborne radar. He reported that:
"the Bogey was traveling very slowly and after closing to 400 feet our craft held position for 3 minutes and finally got visual contact. Bogey was a Japanese single-engine dive-bomber (Kate). 90 rounds of 20-mm was fired point blank into the enemy plane. The fire was plainly seen to enter the right wing and fuselage. By accident cockpit lights flashed on in our craft blinding pilot and preventing further observation."
<end snip>.
Why did he hold for 3 minutes to get visual? To verify friend/foe? I've seen other accounts of v-kills at night. This is but one example.
Otherwise, the closing speed issue is potentially valid, depending on the interceptor in use. However, of the known types used in nightfighting (P-61, 110, 219, P-70, P-38, F6F, FW190, Ju-88/188/388, others) I don't see why this would be such a huge problem.
