That is pretty much guaranteed not to happen. There isn't even ipq60xx support in master, it won't be there for the upcoming openwrt-23.05 and will take months+ at best to eventually/ hopefully make it to master (and ipq6000 (rather than ipq601x and upwards) is even more questionable to 'ever' get support, 256 MB RAM is pretty much guaranteed to be impossible as well.
If you want to see ipq60xx support -for devices with ipq601x and >=512 MB- in a stable release, help working on getting it into master, so it will end up in the next release afterwards quite naturally. Backporting whole targets to already branched releases is not going to happen.
tl;dr: chances for this device to ever get OpenWrt support are close to zero, even less for 22.03.x.

256 MB RAM and ath11k is a hard no-go, as ath11k is quite memory hungry and already needs to be pretty lobotomized to deal with 'just' 512 MB RAM.
