Tp-link tl-mr6400 v5.3

Hi, I have a question about installing openwrt on TP-LINK TL-MR6400 V5.3. I see that the V5.0 version has OpenWRT support but I am interested if anyone has tried to install this firmware on a V5.3 router? My company uses this software on routers and I am looking for a replacement for my customers' current hardware. As I only have access to V5.3 I urgently need to know the answer regarding openwrt support for this model.
Thank you in advance for your help.
