Yeah, there'll be lag.
As CZroe says, you need the cathode ray tube drawing line by line to get the Zapper to work, and no lag (the AVS has no output lag, but anything in the signal chain like that converter would introduce it.) And the only 720p CRT TVs wouldn't do the interlacing that the Zapper needs.
Someone did introduce a Frankenstein'd setup using a Rasberry Pi, a Wiimote and sensor bar, and an LED and an Adafruit Trinket Pro.

However, he was using a regular NES with composite output split between the TV and the setup. I don't know if there's a similar one for HDMI.
I've tested Hi-Def NES and, even though the analog output only shows white silhouettes of the sprites on a black screen while outputting HDMI, the Zapper still works for some games. Full-screen flashes don't work because only sprites/objects show on the analog screen with HDMI in use, but the hit boxes do show.
This means you can't start Duck Hunt with the Zapper (full-screen flash), but you can start with the controller and shoot the ducks/targets with the Zapper. Most people use the controller to select Duck Hunt from the SMB/DH menu anyway and never realized you could navigate the menu with the Zapper, so Duck Hunt is perfectly playable with this hack and a Hi-Def NES, which is pretty cool.
